Linear Amplifier Boasts 80 W Output Power

April 12, 2007

By providing wideband operation in a compact and lightweight form, a solid-state Class AB linear power amplifier (PA) satisfies a variety of military needs. The model BM2719-80-3, which spans 20 to 1000 MHz, boasts RF output power of 80 W. Its RF gain is 50 dB ±1.5 dB. The PA's RF-input overdrive is +10 dBm. Input voltage standing wave ratio (VSWR) is 2.12:1 maximum. The device's harmonic rejection is –13 dBc. Among the other specifications for the model BM2719-80-3 are –60 dBc spurious content, 9.5 A typical DC current draw from a +28-VDC supply, and 20-µs PA enable speed. The PA measures 6.4 X 3.4 X 1.06 in. and weighs 1 lb.
