Coaxial Circulators and Isolators up to 40 GHz
Coaxial circulators and isolators operating up to 40 GHz provide directional signal control and protection for sensitive receiver stages in modern RF systems. These passive components manage signal flow and isolate reflected power in applications ranging from wireless infrastructure to defense radar platforms.
The extended frequency coverage addresses requirements in both commercial telecom and military systems where impedance management and signal integrity are critical design parameters.
Technical Specifications
- Frequency Range: DC to 40 GHz with band-specific configurations
- Insertion Loss: Typically 0.3 to 0.8 dB depending on frequency and model
- Isolation: 15 to 25 dB minimum across operating bandwidth
- VSWR: <1.5:1 standard performance
- Connectors: SMA, 2.92mm, and customized interfaces
- Housing Options: Coaxial cartridge, drop-in, surface-mount (SMT) packages

Applications
- 5G/6G Infrastructure: Base station receiver protection and duplex signal separation
- Defense & Military Systems: Radar frontends, electronic warfare equipment, and secure communications
- SATCOM Networks: Uplink/downlink isolation in satellite transponders and ground terminals
- Test & Measurement: Reflection reduction in network analyzer ports and signal conditioning
- Point-to-Point Microwave: Frequency-selective isolation in repeater and relay systems
- mmWave Antenna Systems: Phased array protection and beamforming network integration
Dual-junction circulators, drop-in configurations up to 26.5 GHz, and SMT variants up to 15 GHz offer design flexibility for retrofit and new platform development. High-power models accommodate transmitter stages where standard isolators face thermal limitations.
bq-microwave collaborates with manufacturers including AT Microwave to deliver certified components meeting industry specifications for insertion loss, bandwidth flatness, and reliability. Technical support is available for integration into complex RF systems.
