Ka-Band Latching Circulator-Isolator

TRAK Microwave announces a new Ka-Band Dual-Junction Latching Circulator-Isolator for high performance satellite communications links, commercial aviation systems, missile systems, and other high-rel aerospace applications. The unit can be designed to cover a variety of bandwidths across the 16-35 GHz range and offers 1 µs switching speed and a very low insertion loss of 0.2dB in transmit mode and 0.4dB in receive mode. The device will handle +39dBm transmit power with 25dB isolation to protect the receiver while transmitting, and is well matched with 25dB return loss and better than -60dBc RF leakage.

The suspended circulator-isolator ferrite element is supported with a temperaturestable dielectric material, avoiding the thermal variations of commonly-used PTFE, and employs an innovative field-cancelling technique minimizing external magnetic interference. The device is space-qualified, and TRAK can integrate the latching junction design into complex multi-function assemblies suitable to the customer’s specifications.
