Belar FM RF Amplifier RFA-1 Radio Station Amp Monitor
Manual can be found at: http:// /ib/RFA-1_Comp.pdf
This is an FM RF amp that came out of a radio station.
"The Belar RFA-1 FM RF amplifier is a sensitive, high gain, all silicon, solid state amplifier designed to meet the requirements of the broadcaster for off-air monitoring of both monaural and multiplexed FM transmitters in the 88-108 mHz band.
The RFA-1 utilizes an IF of 10.7 mHz with a phase linear bandwidth of 600 kHz to unsure low distortion of a multiplexed signal. The IF skirt selectivity is such that an adjacent channel 800 kHz removed is 50 dB down."
"The RFA-1 is a solid state, sensitive, high gain RF amplifier consisting of an RF preamp, a balanced mixer, a 10.7 mHz IF strip, a balanced modulator, an RF postamp, and a crystal oscillator."
The sticker on the back reads "factory tuned to 89.9"
