Circulators up to 40 GHz

Coaxial Circulators up to 40 GHz are essential components for modern RF and microwave systems, providing reliable signal direction control with minimal insertion loss. bq-microwave offers high-performance circulators for demanding telecommunications, radar, and satellite applications.

Key Features

• Frequency range up to 40 GHz – complete coverage for S-, C-, X- and Ku-band applications
• Low insertion loss and high port-to-port isolation for maximum signal integrity
• Standard coaxial, dual junction, and drop-in packages for flexible system integration
• SMT variants up to 15 GHz for compact PCB layouts
• Thermally optimized designs for continuous and pulsed high-power applications

Applications

• Telecommunications systems and 5G/6G infrastructure
• Radar applications (FMCW, pulsed, CW)
• SATCOM and defense systems
• Test and measurement instruments with strict isolation requirements
• HPA and LNA protection circuits

Circulators enable bidirectional signal routing with asymmetric propagation: signals from port 1 pass to port 2, from port 2 to port 3, and from port 3 back to port 1. This characteristic makes them indispensable for duplexing, high-power amplifier isolation, and reflection protection in sensitive RF front-ends.
