Product Description

TPRD-1544F - Pass-Reject Base Station Duplexer - 148-174 MHz

The Telewave TPRD-1544F allows simultaneous operation of a transmitter and receiver into a common antenna. This pass-reject duplexer utilizes folded four-inch cavities to achieve high “Q” in a compact size. Telewave folded cavities utilize a special construction technique and circuit design which allow a physically shorter cavity to produce nearly the same performance as a standard length cavity.

The TPRD-1544F duplexer uses two folded pass-reject cavities in the transmitter and receiver sections, for frequency spacing of 2 MHz or more. Selectivity and insertion loss may be adjusted by rotating the calibrated connector loops.This duplexer is designed to mount horizontally on a 19” rack. Spacing brackets are available to allow mounting in a cabinet with 5” or 8” depth from the front.

Telewave duplexers feature cavities with ¼” aluminum top plates, which are fully welded to the aluminum outer conductor. Silver-plated tuners, beryllium copper finger stock contactors and threaded Invar rods assure maximum temperature stability, and many years of trouble-free operation. All duplexers are tuned and tested with customer-specified frequencies prior to shipping. If frequency changes are required, the positive locking mechanism allows for straightforward field tuning by rotating the threaded Invar rod.
