S Band 2.9–3.4GHz Dual-Junction Coaxial Circulator

High-Isolation Coaxial Circulator for S Band RF Front-End and Transmit Systems

HzBeat's 2.9–3.4GHz Dual-Junction Coaxial Circulator is designed for S band RF systems requiring enhanced isolation, low insertion loss, and reliable coaxial integration.
The dual-junction structure supports stronger reverse-signal suppression than a standard single-junction circulator, making it suitable for transmitter chains and RF front-end protection.
The device provides P1–P2 insertion loss of 0.3 dB, P2–P3 insertion loss of 0.6 dB, P2–P1 isolation of 20 dB, P3–P2 isolation of 40 dB, and multiple connector options including N-K, N-J, SMA, and TAB.

2.9-3.4GHz S Band Dual-Junction Coaxial Circulator

Key Features & Advantages

S Band 2.9–3.4GHz Coverage: Designed for S band radar, communication, and RF front-end systems requiring stable circulation.
Dual-Junction Design: Provides enhanced isolation performance for applications that need stronger reflected-signal suppression.
Low Insertion Loss: P1–P2 insertion loss is 0.3 dB, while P2–P3 insertion loss is 0.6 dB, supporting efficient RF signal routing.
High Isolation Path: Isolation reaches 20 dB from P2 to P1 and 40 dB from P3 to P2 for improved port-to-port protection.
Flexible Connector Options: N-K, N-J, SMA, and TAB options support different module layouts and system integration requirements.
Pulse Power Capability: Supports 500W peak power with 500us pulse width and 10% duty cycle for pulsed RF applications.
