Delta Meccanica 600 Watt Band Pass FM Filter triple cavity (P.N. 20001/3-L)

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 Tripple cavity FM filter with N-output connector prevents intermodulation at transmitters with a power up to 600 watts.
