Description

A double-ridge waveguide (DRWG) loop coupler is a broadband directional coupler designed for high-power RF and microwave systems. It’s especially useful in applications like radar, satellite communications, and EW systems where wide bandwidth and precise coupling are essential. Key Specifications: - Frequency Range: Typically from 0.84 GHz to 40 GHz, depending on the WRD waveguide size (e.g., WRD840, WRD180). - Coupling Values: Standard options include 20, 30, 40, 50, and 60 dB, with ±1.5 dB accuracy. - Directivity: Around 12–15 dB, ensuring good isolation between ports. - VSWR: As low as 1.15:1, minimizing reflections. - Power Handling: Suitable for high average and peak power levels—some models handle up to 10 kW peak. - Connectors: SMA, N-Type, or 2.92 mm, depending on frequency and power requirements. - Construction: Aluminum or copper with Surtec or chromate finishes for corrosion resistance and MIL-STD compliance.
