Description

The Lectrosonics PF25 Block 20 is a passive antenna filter designed to suppress unwanted RF signals and noise outside the 512–537.5 MHz operating band. Installed in the coaxial line between a receiving antenna and a receiver or multicoupler, it provides additional filtering to help reduce interference and intermodulation in wireless microphone systems.

Its bidirectional circuitry passes DC bias power to a remote antenna amplifier while carrying the received RF signal toward the receiving system. Suitable for use with Venue receivers, UMC16B multicouplers and more complex antenna distribution systems, the PF25 combines standard BNC connections with a compact metal housing manufactured in Rio Rancho, New Mexico.

Features

Block 20 RF Filtering
Filters antenna signals for the 512–537.5 MHz operating band, helping reject unwanted signals outside that range.

Surface Acoustic Wave Technology
A SAW filter provides additional selectivity to help reduce out-of-band interference and intermodulation.

DC Power Pass-Through
Passes DC bias power from a compatible receiver or multicoupler to a remote antenna amplifier.

Bidirectional Circuitry
Allows RF signals and antenna amplifier power to travel in opposite directions through the same coaxial connection.

Flexible System Integration
Use with a single receiver or multicoupler, or incorporate it into a distribution system that feeds receiving equipment in different frequency bands.

Standard BNC Connections
Connects directly into 50-ohm coaxial antenna lines using standard BNC connectors.

Rugged Metal Housing
A compact metal enclosure provides durable construction for professional receiving antenna systems.

Made in the USA
Manufactured in Rio Rancho, New Mexico.
