The Diamond MX72N duplexer is a commercial-grade, high-isolation RF signal routing module engineered to facilitate the simultaneous operation of dual-frequency transceivers or distinct antenna systems over a shared feedline network. Enclosed within a ruggedized, heavy-duty metallic shielding block measuring a compact 46 x 25 x 57 mm, this premium passive splitter isolates specific frequency bands to prevent cross-modulation and inter-port interference. It functions as an essential, high-rotation operational utility component for multi-band base stations, complex vehicular emergency installations, technical radio service benches, and high-volume B2B radiocommunication accessory wholesale networks across European markets.
The internal RF architecture of this device, features an advanced low-pass and high-pass filtering design optimized to distribute signals across a vast frequency spectrum spanning 1.6–30 MHz, 140–150 MHz, and 400–460 MHz. Designed to handle elite power thresholds, it manages up to 400W CW (1kW PEP) on HF bands, 150W CW (400W PEP) on VHF, and 100W CW (250W PEP) on UHF ranges. Fitted with an integrated SO-239 (PL female) input socket on the chassis and terminating in two heavy-duty flexible pigtailed leads—one outfitted with an N-type male (NJ) plug and the other with an MJ (PL-259) male connector—it establishes a vibration-proof mechanical bond, keeping active dual-band infrastructures operating at absolute readiness.
