Cobham launches new X-Band coaxial limiter

Posted on 15 June, 2018 by Advance 

Cobham Advanced Electronic Solutions has announced the launch of the ACLM5022C110, a new 8 to 12 GHz X-band coaxial limiter, providing high performance in a compact package.

The limiter provides an ideal solution for receiver protection in radar, electronic warfare (EW), electronic countermeasures (ECM), communications and test systems.

As higher power requirements emerge for receiver protection, delivering performance in an attractive form factor across a wide temperature range emerges as a challenge. To solve this problem, the ACLM5022C110 features power handling rated at 25W CW over the full temperature range from -55°C up to 85°C, demonstrating significantly higher power handling for this type of package. 

The limiter features maximum flat leakage of +15dBm and recovery time of 200nsec maximum. Peak power handling is 150W maximum at 1usec pulse width and 1% duty cycle.  When operating in a small signal environment, insertion loss is less than 1.5dB and VSWR is less than 1.5:1. In order to facilitate system integration, I/O DC blocks are incorporated in the limiter. The compact design features field replaceable SMA connectors which can be removed for drop-in microstrip or stripline applications.

Hermetic seal and MIL-screening are available upon request. The limiter can be customized to accommodate additional frequency ranges, mechanical package requirements, and connector configurations.
