CIR3C-440-50-01 - UHF circulator, 420 - 460 MHz, 50 W, N female

UHF RF Circulator 420–460 MHz 50 W with N-type Female Connectors

The CIR3C-440-50-01 is a coaxial RF circulator designed for professional applications in the 420–460 MHz UHF band. This three-port 50-ohm circulator is used in UHF radio systems to improve isolation between transmitter and antenna and to protect UHF power amplifiers from reflected power and impedance mismatches.

The circulator routes the RF signal in the correct direction and diverts reflected power toward a termination load, contributing to system stability and operational continuity. Thanks to its coaxial construction and N-type female interfaces, the device can be easily integrated into RF equipment and infrastructure operating in the 420–460 MHz frequency range.

Main features and RF system integration

Designed as a 50 W UHF RF circulator, the device is suitable for continuous operation in industrial and professional environments. Its industrial-grade construction, combined with compliance with RoHS and REACH directives, makes it suitable for use in European and international projects requiring reliability and repeatable performance.

Typical applications in the 420–460 MHz UHF band

• Professional UHF radio networks and PMR systems for industrial and service applications
• Public safety communication systems and radio networks dedicated to emergency services
• Radio communications for transportation and logistics in complex environments such as ports, airports, and construction sites
• Industrial telemetry and control systems operating in the UHF band
• Protection of UHF power amplifiers in transmission chains and radio repeaters
• RF laboratories and test benches for testing equipment operating from 420 to 460 MHz
