Description
Ascentta’s ultra-broadband circulators, covering 1290nm to 1620nm, already boast high directivity and return loss, each with minimum values of 50dB. However, we are always looking for ways to improve our designs, which leads us to introduce the high directivity version of our ultra-broadband circulator.
These circulators cover the same range of wavelengths as our standard ultra-broadband circulators, but now with over 72.5dB of directivity, and a return loss of at least 70dB. The insertion loss is less than 2.5dB (both 1 to 2 and 2 to 3), a small change over that of the standard ultra-broadband design.
NOTE: Attached datasheet is for our standard ultra-broadband circulators, not our high directivity circulators.
