Description

The Amphenol-Procom MPX2/6 H-4/6-N(f) mini-duplexer is a compact duplex filter designed for VHF transceivers operating in the 152-175MHz band with 4-6MHz duplex spacing between Tx and Rx. Designed for space-constrained environments, it integrates six high-quality cavities with temperature-compensated helical resonators.

Developed for use on single Tx/Rx frequencies, it guarantees insertion loss below 1.5dB, isolation above 90dB in the Tx†’Rx direction and VSWR below 1.4:1. The extruded aluminum construction with steel chassis and Teflon-insulated coaxial cabling is covered in corrosion-resistant black vinyl, with female N connectors and compact dimensions (118.5x154x33mm). Ideal for professional duplex applications with high performance requirements.
