The PTS6900 Solid State Power Amplifier (SSPA) is a low band CW amplifier operating within the 2 to 6 GHz frequency range ideally used for EW/ECM applications. The module incorporates an internal EMC filter on the 28 V input for full compliance with EMC requirements, a fast RF mute capability that enables RF output to be muted in less than 1 µs, and a built-in test capability used to monitor the internal DC to DC converters and baseplate over-temperature.
