Ultra-broadband amplifiers have output power of tube amplifiers in compact, solid-state modules

By

Qorvo has introduced three new solid-state power amplifier (SSPA) modules that further expand the power and frequency range of the company’s Spatium® amplifier family. The modules are optimized for electronic warfare applications, enabling defense customers to use ultra-wideband SSPA technology as an alternative to traveling wave tube amplifiers (TWTAs). “The need for wider bandwidth, higher frequency […]
