Reverse signal reflection is a major hidden risk that destabilizes systems and damages transmitter modules in private networks, wireless base stations and RF transmission systems. As an essential passive component for link protection, a high-performance circulator largely decides the reliability of the entire RF system.

The 5o1035380380400NK RF coaxial circulator from 5o.com covers the 380~400MHz UHF band. With low insertion loss, superior isolation and balanced high-power capacity, it builds a stable unidirectional signal barrier for industrial wireless communication equipment.

 This circulator stands out with premium electrical performance. Its maximum insertion loss is only 0.3dB, keeping signal attenuation minimal during forward transmission to preserve RF energy and cut system power waste. Minimum isolation hits 23dB to effectively block reverse reflected signals and protect expensive components such as power amplifiers and RF sources. The VSWR is 1.2, delivering excellent impedance matching and less port reflection for smooth link operation. It handles 300W forward power and 300W reverse power, sustaining stable performance under continuous high-power transmission.

 It adopts N-Female connector with standard 50Ohm impedance, compatible with mainstream RF cables, antennas and chassis ports for easy installation and commissioning. With compact dimensions of 35×38×15mm, it supports high-density integration and saves valuable internal space inside equipment. It features outstanding environmental resistance. The operating temperature spans -40? to +85?, reliably serving outdoor cold scenarios and hot industrial cabinets. The storage temperature ranges from -55? to +125?, resisting extreme temperature impact during storage and shipment.

 Besides standard off-the-shelf units, 5o.com offers custom design service. We can tailor frequency band, power rating, connector style and mechanical structure to match project requirements. It is widely applied in rail transit communication, UHF private network base stations, wireless telemetry and RF test systems. Every unit passes strict performance testing before delivery, backed by a 1-year warranty to bring peace of mind for your procurement and long-term operation.
