Delta Meccanica 1.2kW Band Pass FM Filter triple cavity (P.N. 20071/3)

When transmitters are close together or multiple transmitters are used in the same location, new frequencies can be formed, called “intermodulation.” Because these frequencies must be strongly suppressed, a cavity filter must be placed after each output of the transmitter or output stage. If the frequencies of the FM transmitters are closer together than 2 MHz then a triple cavity filter is required. The cavity filter must be rated for the power of the transmitter or output stage. This Delta Meccanica 1.2 kW Band Pass FM Filter tripple cavity FM with 7/8″ output connector prevents intermodulation at transmitters with power up to 1200 watts.
