Dolph Microwave
Double Ridged Waveguide Couplers

Waveguide coupler, typical main line standing wave VSWR1.10, auxiliary line standing wave VSWR1.25 within 20% of the waveguide bandwidth, typical coupling degree is 20/25/30/35/40/45/50 / 60dB. Due to its compactness The structure and good sealing performance are widely used in microwave systems below 12G. Because the bandwidth of the double-ridged waveguide ranges from octave to triple octave, such wide bandwidth makes it difficult to design the high-directional coupler of the double-ridged waveguide. Dolph microwave products have reached and close to the level of imported products, can replace imported broadband high-power ridge waveguide system.

FAQs of Double Ridged Waveguide Couplers

FAQs of Double Ridged Waveguide Couplers
  • Description of Double Ridged Waveguide Couplers

The double ridge waveguide couplers are very similar to coax couplers and are a basic microwave device used in most microwave systems, test sets and applications for monitoring RF power. These microwave waveguide components allow for monitoring of power without altering the characteristics of the transmission line.


  • Application of Double Ridged Waveguide Couplers

The double ridge waveguide couplers can be used for test and measurement for calibration, as well as system interlocks.
