Power devices are for airborne, mobile, and fixed-site electronic warfare (EW) and radar transmitters where space, cooling, and power are limited.

MELVILLE, N.Y. – Comtech PST Corp. in Melville, N.Y., is introducing the model BME2969-300 integrated high-power-density solid-state RF power amplifier modules for airborne, mobile, and fixed-site electronic warfare (EW) and radar transmitters where space, cooling, and power are limited.

The model BME2969-300 has a frequency range of 2000 to 6000 MHz; saturated power output of 300 Watts; output power into 2.0:1; voltage standing wave ratio (VSWR) of 200 Watts minimum; RF input range of -10 to 0dBm typical; and RF input Overdrive of +10 dBm maximum.

The power electronics device offers DC bias of AB linear; modulation format of multi-tone, CW, AM, FM, pulse; input VSWR of 2.0:1 maximum; output load VSWR of 2.0:1 typical; harmonic (in band 2nd/3rd) of less than -20 dBc typical; IM products (4 tones) of less than -20 dBc typical; spurious of less than -60 dBc; stability of open/short tested; built-in test of composite fault indication; RS-422 (over temp, over current); forward/reverse Sample Analog Voltage; noise power output of biased -70dBm/Hz Typical; and quieted -150dBm/Hz typical.
