Description

The PRO MPHY450 2 3dB N hybrid combiner is designed for professional radio applications in the 380-475MHz band, allowing you to combine or split RF signals between two transmitters or receivers with a single antenna. The ring hybrid structure ensures high reliability, low insertion loss, and excellent channel separation, even at very close Tx frequencies.

It offers symmetrical 3dB division (1:1) with less than 3.4dB loss over ±5MHz and greater than 35dB port isolation. It supports up to 30W per channel in combiner mode (with adequate heatsink) and up to 60W in divider mode, thanks to the integrated 30W internal load. 50? impedance on all ports, with VSWR <1.5:1. Includes female N connectors and compact design for easy integration into racks or radio cabinets.
