2.1Bandpass filter PPF-1602/R3K KD ALVR.468874.001 is designed for use in the antenna-feeder path of receiving and transmitting devices and locomotive radios with impedance 50 Ohm, operating in the frequency band 151,7 - 156,0 MHz. Contributes to increasing the selectivity of receivers and reducing the influence of out-of-band interference.
The use of filter allows you to get rid of the effect of blocking high-frequency signals from nearby radio transmitters and reduce the sensitivity of the receiver, as well as eliminate the occurrence of intermodulation losses. Installing a filter in the transmitter circuit reduces the level of out-of-band radiation of the transmitting path and prevents the appearance of intermodulation products from external sources of radiation.
