Description

17.7-19.7GHz WR-42 WAVEGUIDE COUPLER

  • Passive device – no external power required

  • Stable performance over temperature and vibration

  • Excellent VSWR at all ports (when properly terminated)

How to Use a WAVEGUIDE COUPLER (Usage Method)

  1. Identify all four ports –
    A WAVEGUIDE COUPLER has clearly labeled ports: Input, Through/Output, Coupled, and Isolated.

  2. Connect main line in series –
    Insert a WAVEGUIDE COUPLER directly into the transmission line, with the input port facing the source and the through port facing the load.

  3. Terminate the isolated port –
    Always terminate the isolated port of a WAVEGUIDE COUPLER with a matched WAVEGUIDE LOAD to prevent reflections and maintain directivity.

  4. Connect the coupled port to a detector –
    Connect a power meter, spectrum analyzer, or detector diode to the coupled port of the WAVEGUIDE COUPLER for signal sampling.

  5. Observe the coupling direction –
    A WAVEGUIDE COUPLER is marked with an arrow indicating the forward direction; reverse installation will reduce coupling to the intended port.

  6. Match flange types –
    A WAVEGUIDE COUPLER requires the same flange type (UG, CPR, cover, or choke) as the rest of the waveguide system.

  7. Power rating verification –
    Before using a WAVEGUIDE COUPLER, verify both the average and peak power ratings for the main line.

  8. Check coupling value –
    Select a WAVEGUIDE COUPLER with the appropriate coupling coefficient (e.g., 10 dB for high‑power sampling, 40 dB for low‑level monitoring).
