Comtech PST introduces a new high power density solid state RF module

June 2, 2014

 

Comtech PST proudly introduces a new high power density solid state RF module. Comtech’s latest development continues to expand on its proven innovative integrated RF GaN power amplifier designs by further increasing the RF power density. Consistent with its planned technology development roadmap, Comtech proudly introduces the latest in GaN-based 6-18 GHz RF amplifier. This highly integrated design is ideal for use in communication, electronic warfare, and radar transmitter systems where space, cooling, and power are limited.
