A double-ridge straight waveguide is a broadband transmission line designed for high-frequency RF and microwave applications where wide bandwidth, low loss, and compact size are critical. 📡 Key Technical Features: - Structure: Rectangular waveguide with two internal ridges running parallel to the narrow wall. These ridges lower the cutoff frequency and support a broader single-mode bandwidth. - Frequency Range: Typically from 0.84 GHz to 40 GHz, depending on the waveguide size (e.g., WRD840, WRD1800). - VSWR: As low as 1.15:1, ensuring excellent impedance matching. - Length Options: Standard lengths range from 100 mm to 500 mm, with custom lengths available. - Materials: Usually aluminum or copper, with surface finishes like chromate conversion or silver plating for corrosion resistance and conductivity. - Flanges: Compatible with standard double-ridge flanges (e.g., FP/FM), customizable for system integration. 🛠️ Applications: - Test setups requiring broadband signal transmission. - Radar and EW systems where compact, high-power handling is needed. - 5G and mmWave communications for wideband interconnects.
