VHF 6 cavity, square duplexer, 136-174 MHz, 350W, N-type female in/out - specify transmit and receive frequency

Product code: ZDX1317-NF-6

The ZDX1317-NF-6 VHF Cavity Duplexer is a high-performance RF filter designed for base station applications requiring high power and close frequency separation. Engineered to efficiently combine two frequencies or serve as a pre-selector, it ensures low insertion loss and high isolation for optimal signal clarity. This VHF duplexer features a six-cavity design, with field-adjustable capacitors allowing precise selectivity. Built for durability, each cavity is temperature compensated for operation between -40ºC and +65ºC, with silver-plated tuning rods and loops enhancing conductivity. Supporting frequencies within 136-174MHz, the ZDX1317-NF-6 delivers exceptional rejection and stability, making it an ideal choice for demanding RF environments. With N-Female connectors and a rugged construction, it ensures reliable performance for commercial and critical communications.
