The RES-INGENIUM FM1K-108 is a highly reliable, highly compact, and high performance 1 kilowatt FM amplifier module.
This Class B amplifier was designed specifically for FM and HDFM radio broadcast applications, and features robust built-in protection circuitry, compact size: 250mm x 180mm x 53mm [9.8” x 7.1” x 2.1”], and no tuning required for full operation.
The built-in protection circuitry provides maximum security against overdriving, SWR over-voltage, and thermal runaway. This amplifier provides 1kW of linear CW output power (from 87.5MHz to 108MHz), a substantial 74 per cent collector efficiency, and superior harmonic suppression (-55dBc).
The FM1K-108 is extremely rugged and reliable, featuring four MRF6V2300NBR1 LDMOS transistors from Freescale Semiconductor.
The enhanced gain (22dB) allows the system designer to use lower input power (7W), eliminating one or more gain stages, and saving cost. It is ideal for FM transmitter, transposer, and broadcast exciter designs.
