waveguide wideband circulator

Huasen Microwave:Waveguide Wideband Circulator Product Introduction

The Waveguide Wideband Circulator manufactured by Huasen Microwave operates on the principle of ferrite materials' non-reciprocity. Under the action of a constant magnetic field, it enables unidirectional electromagnetic wave transmission in a specific sequence. Its core function is to serve as a transceiver duplexer for pulsed radar, achieving isolation between transmitted and received signals. It provides matching isolation between stages in the system to reduce signal reflection interference.

Our Product Classification and Technical Parameters

• Standard Waveguide Wideband Circulator

• Waveguide Differential Phase-Shift Circulator (for Wideband Applications)​​​​​​​：Application Scenario: Scenarios requiring phase control in high-power radar systems.​​​​​​​​​​​​​​

Design Features

-Material optimization: Silver-plated copper is adopted in the high-frequency band to enhance thermal conductivity.​​​​​​​​​​​​​​     

• High-Power Waveguide Wideband Circulator

Why Choose Our High Power WG Differential Phase Shift Circulator?

Waveguide Broadband Circulator (also referred to as Waveguide Full-Band Circulator) is a type of high-performance microwave passive component offered by Huasen Microwave, boasting the following advantages and features:

1..Broadband Coverage：Compared with standard waveguide circulators that typically have an operating bandwidth of ≤5%~15%, the waveguide full-band circulator can work within the entire waveguide dominant mode frequency band It enables "full-band" continuous use without the need for device replacement.

2.Excellent Electrical Performance Indicators：

• VSWR: Typ ≤1.35 (low freq) / ≤1.25 (high freq), excellent matching.
• Insertion Loss: ≤0.5 dB (general), down to ≤0.3 dB (high freq), high transmission efficiency.
• Isolation: ≥20 dB, anti-crosstalk, stable system performance.

3.Reliable Structure and Mature Technology

4.Wide Applications：Suitable for radar, communication, electronic countermeasure and test systems requiring broadband, high isolation and low insertion loss.Ideal for scenarios needing full waveguide band coverage without frequent device replacement.

Product Features & Process

• Reverse propagation and mutual coupling separate signals, avoiding reflection crosstalk.
• Average power up to 3500W, suitable for high-power applications such as radar.
• Customizable structural design (including waveguide, Y-junction, ferrite/magnet layout).
