Description

Mini 0.6–6 GHz Analog Wideband Transceiver Module

The Mini 0.6–6 GHz Analog Wideband Transceiver Module is a compact, cost‑effective fiber optic transmitter/receiver solution designed for demanding RF over fiber (RFoF) applications. Covering a continuous bandwidth from 0.6 GHz to 6 GHz, this module enables transparent transport of analog RF signals over single‑mode optical fiber while maintaining excellent linearity and a very high spurious‑free dynamic range (SFDR). Its flat frequency response and low noise performance make it well suited for modern broadband wireless, radar, and satellite ground station infrastructures where low distortion and stable amplitude response are critical.

Designed as a matched transmit/receive pair, the module performs both RF‑to‑optical and optical‑to‑RF conversion to form a full two‑way RF link. On the RF side, standard 50 Ω SMA interfaces allow straightforward connection to existing RF front‑ends, test equipment, or distribution networks. On the optical side, the module uses 9/125 µm single‑mode fiber and operates at industry‑standard 1310 nm or 1550 nm wavelengths, ensuring compatibility with common telecom‑grade components and long‑haul fiber deployments. The integrated high‑performance InGaAs photodiode in the receiver and linear, optically isolated FP/DFB laser in the transmitter are engineered to preserve signal integrity over the full operating bandwidth.

The transceiver is housed in a tight, cast metal enclosure that provides excellent shielding against electromagnetic interference and enhances thermal stability in field environments. Its compact footprint makes it easy to integrate into space‑constrained racks, radios, and embedded platforms, while the FC/APC optical connectors support low back‑reflection operation demanded by high‑performance analog links. With typical RF link gain around 0 dB and stable behavior across 0.6–6 GHz, the module behaves as a nearly transparent fiber extension of coaxial RF lines, significantly reducing loss over distance and simplifying remote antenna or sensor placement.

This wideband analog RFoF module is ideally suited for WiMAX and 4G LTE networks, 5G communication trials and deployments, shipborne RF distribution systems, and satellite earth station infrastructures where RF signals must be transported over tens to hundreds of meters or more without degrading dynamic range. It is also appropriate for distributed antenna systems (DAS), phased‑array radar distribution networks, remote LO / reference distribution, and cable replacement in test and measurement setups. The wide operating temperature range and robust design allow the module to be deployed in indoor equipment rooms as well as more challenging field or shipboard environments.

For system designers, the module offers a practical way to migrate from traditional coax‑based RF runs to fiber‑based links, reducing cable losses, weight, and susceptibility to electromagnetic interference. With support for 1310 nm and 1550 nm operation, standard single‑mode fiber, and FC/APC interfaces, it integrates seamlessly into existing optical infrastructures. Combined with its broad modulation bandwidth option (0.6–6 GHz configuration), the Mini Analog Wideband Transceiver Module provides a flexible platform for current and next‑generation RF communication and sensing systems that demand high linearity, wide bandwidth, and stable long‑distance transmission.

Frequently Asked Questions

What is the Mini 0.6–6 GHz Analog Wideband Transceiver Module and what does it do?

The Mini 0.6–6 GHz Analog Wideband Transceiver Module from Beijing Rofea Optoelectronics is a compact RF‑over‑fiber link module. It converts RF signals in the 0.6 GHz to 6 GHz band into optical signals and back again, enabling low‑loss transmission of wideband RF over single‑mode fiber. A typical link consists of one transmitter module (RF‑to‑fiber) and one receiver module (fiber‑to‑RF), providing a high spurious‑free dynamic range (SFDR) and flat frequency response for applications such as 4G/5G wireless, WiMAX, satellite earth stations, and shipborne RF distribution. It uses 1310 nm or 1550 nm FP/DFB lasers and high‑performance InGaAs photodiodes, with FC/APC optical connectors and 50 Ω SMA RF ports.

What are the key specifications and performance characteristics of this 0.6–6 GHz RF over fiber module?

Key specifications include: - RF bandwidth: 0.6 GHz to 6 GHz (modulation option “03” in the ordering code) - Frequency response flatness (0.6–6 GHz): typically ±1.5 dB, max ±2 dB - RF link gain: −5 to 0 dB (typical end‑to‑end gain for a matched Tx/Rx pair) - Input RF power (nominal): −5 dBm - Maximum RF input power (Tx): 10 dBm - Optical output power (Tx): 2–4 mW - Operating wavelengths: 1310 nm and/or 1550 nm (versions 13 or 15 in the part number) - Impedance: 50 Ω RF ports via SMA connectors - VSWR: typically ≤ 1.5 - Supply voltage: 4.5–5.5 V DC (nominal 5 V) - Total supply current: ~100 mA (per module, typical) - Operating temperature: −25 °C to +65 °C; storage: −40 °C to +85 °C These specs are comparable to other RFoF links on the market (e.g., 0.1–6 GHz or 0.5–6 GHz links from similar vendors) and are suitable for high‑dynamic‑range analog RF transport.

How do I integrate and power the Mini 0.6–6 GHz Analog Wideband Transceiver Module in my RF over fiber system?

To integrate the module: 1) Power: Provide a regulated 5 V DC supply within 4.5–5.5 V to each module. Allow at least 100 mA per module and follow good grounding and decoupling practices. 2) RF connections: Connect your RF source to the Tx SMA port and your RF load/receiver to the Rx SMA port using 50 Ω coaxial cables. Ensure the nominal RF input is around −5 dBm and never exceeds 10 dBm at the Tx. 3) Fiber connections: Use 9/125 μm single‑mode fiber with FC/APC connectors to minimize back‑reflection. Typical link lengths are similar to other low‑power RFoF modules (tens of kilometers for 1550 nm in low‑loss fiber; exact reach depends on link budget and any intermediate components). 4) Pairing: Use one Tx and one Rx configured at the same wavelength (1310 nm or 1550 nm). For bidirectional RF, you will typically use two fibers and two transceivers (or a suitable duplex arrangement) to create a two‑way link. Following these steps makes integration similar to other RF over fiber transceivers from FindLight and comparable vendors.

What applications is this 0.6–6 GHz analog wideband transceiver module suitable for?

This module is designed for analog RF over fiber applications that require wide bandwidth and high SFDR. Typical uses include: - 4G LTE and 5G NR remote radio heads and distributed antenna systems (DAS) - WiMAX and other broadband wireless access links - Satellite earth station IF/RF transport (e.g., L‑band to C/Ku/Ka front‑ends, depending on your frequency plan) - Shipborne and airborne RF distribution where long coaxial runs are impractical - RF test ranges and phased‑array antenna remoting - General RF over fiber links in the 0.6–6 GHz band Its flat response and wide dynamic range make it comparable in use cases to other 6‑GHz‑class RFoF modules listed on FindLight and similar technical marketplaces.

What are the ordering options (wavelength, bandwidth, connectors, package) for the Rofea Mini RF over fiber module?

The product code follows the structure: ROF‑MINI‑XX‑XX‑XX. Key options are: - Operating wavelength: "13" = 1310 nm, "15" = 1550 nm (some variants may support both, as indicated in the datasheet). - Modulation bandwidth options: • 01: 10–1200 MHz • 02: 10–3000 MHz • 03: 0.6–6 GHz (this datasheet version) - Encapsulation: "M" indicates module form factor (tight cast metal case). - Connector: "FA" = FC/APC optical connector; "SP" = user‑specified connector. When comparing with similar RFoF products online, confirm that the chosen bandwidth option (e.g., 0.6–6 GHz) matches your intended RF band and that your system uses FC/APC or the requested custom connector type.

What type of fiber and optical connectors are required for this RF over fiber transceiver?

The module is designed for standard single‑mode fiber: - Fiber type: 9/125 μm single‑mode fiber with 900 μm protective coating. - Optical connector (standard): FC/APC (angled physical contact) to minimize back reflection, which is important for stable analog RF performance and laser linearity. You should use matching FC/APC patch cords and adaptors. If your system uses other connector types (e.g., SC/APC or LC/APC often used in comparable RFoF systems), you can either specify "SP" (user specified) in the order code for a custom configuration or use low‑loss, APC‑to‑APC fiber adaptors while maintaining proper return‑loss performance.

What are the operating limits and reliability considerations for long‑term use of the Mini 0.6–6 GHz RF over fiber module?

For reliable long‑term operation: - Temperature: Keep the module within −25 °C to +65 °C during operation and −40 °C to +85 °C in storage. - Supply: Ensure the DC supply voltage stays within 4.5–5.5 V and is clean (low ripple) to avoid distortion or damage. - RF input: Do not exceed 10 dBm at the Tx RF input; operate near −5 dBm for specified linearity and SFDR. - Optical input (Rx): Do not exceed 4 mW of optical power at the receiver input. - Handling: Use standard ESD protection and avoid bending the fiber beyond its minimum bend radius. These conditions are in line with similar RF over fiber systems from other vendors and help maintain high SFDR, flat frequency response, and laser/photodiode lifetime over years of continuous use.
