Product 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)

Identify all four ports –
A WAVEGUIDE COUPLER has clearly labeled ports: Input, Through/Output, Coupled, and Isolated.
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.
Terminate the isolated port –
Always terminate the isolated port of a WAVEGUIDE COUPLER with a matched WAVEGUIDE LOAD to prevent reflections and maintain directivity.
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.
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.
Match flange types –
A WAVEGUIDE COUPLER requires the same flange type (UG, CPR, cover, or choke) as the rest of the waveguide system.
Power rating verification –
Before using a WAVEGUIDE COUPLER, verify both the average and peak power ratings for the main line.
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).
