Broadband Microstrip Circulator

S Band, C Band, X Band, Ku Band, (2GHz-18GHz)

The following products are broadband microstrip circulators designed with a compact form factor, covering the frequency range from the S-band to the Ku-band, with a maximum relative bandwidth of up to 100%.

Key Features & Advantages

Broadband Operation:Covers octave or wider frequency ranges(e.g., 2–4 GHz, 6–18 GHz), simplifying system design.
Compact Size & Light Weight:Planar microstrip design eliminates bulky metal cavities and waveguides, offering a smaller and lighter solution ideal for space - and weight- constrained applications.
High Integration:Surface- mount or direct microstrip bonding enables easy integration with amplifiers, filters, and mixers on PCB, simplifying system assembly.
Excellent High-Frequency Performance:Low insertion loss, high isolation, and high return loss ensure efficient signal transmission, effective reverse protection, and stable system performance.
High Reliability & Stability:All- solid - state design with no moving parts ensures resistance to vibration and shock, delivering stable performance across a wide temperature range.
Cost-Effectiveness: Suitable for standardization and mass production, relatively low manufacturing cost, offering high value.

Typical Applications

Radar Systems: Used in Transmit/Receive (T/R) modules to enable a single antenna to be shared by the transmitter and receiver, isolating the high-power transmit signal from the sensitive receiver.
Communication Systems: Base Stations: Separate transmit and receive signals in TDD systems. Satellite Communication: Transmit-receive switching in both satellite payloads and ground stations.
Electronic Warfare (EW): Used for signal routing and channel switching in reconnaissance and jamming equipment.
Test & Measurement: A key component in test equipment like Vector Network Analyzers (VNAs) to protect the signal source.
Microwave Radio: Used as diplexers in point-to-point communication links.
