PF25 Passive In-Line RF Filter

The PF25 passive, in-line RF filter with a 25MHz passband is designed for use with Lectro VRMWB and VR Field WB wideband receiver systems in cases where the full bandwidth of the receiver is not needed.

The PF25 passive filter is inserted into a coaxial line between the antenna and a receiver or multicoupler to suppress RF signals and noise outside of the desired operating band. It provides the same function as front-end filters in a receiver by reducing interference and intermodulation. The filter will also pass DC “phantom” power from a Venue receiver or UMC16B multicoupler to operate a remote antenna amplifier.

The filter can be used with a single receiver or multicoupler to improve selectivity or used in a more complex signal distribution system where the antenna(s) feed two or more receiving systems in different frequency ranges.
