3W or 10W Amps



The FM-3WA and FM-10WA Broadcast Amp 88-108 MHz

The FM-3WA and FM-10WA are both housed in the enclosure above. The FM-10WA has a front panel power control if you want to turn down the juice. The other control pot is a volume control and is only used if an internal exciter option is ordered. 

We can set up these amps to match your existing transmitter output. Let us know the output level of your transmitter and we'll take it from there. These amps were designed to work with our FMS2 exciter which puts out approximately 350 milliwatts. If your transmitter output is less than this the power output will be reduced unless you order our pre-driver board. Our pre-driver board will work with a signal as low as 10 milliwatts and produce the required 350 milliwatts to drive the output amplifier. 

If your transmitter puts out more than this we simply install a resistive attenuator network to match level requirements. The input and output connectors on the rear panel are both BNC unless otherwise requested. Both units require a regulated 12 volt power supply. The 3 watt unit only needs 1/2 a amp while the 10 watt unit needs about 2 amps.
