Couplers For Waveguide RF Systems

These waveguide directional 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.

Waveguide directional couplers allow for monitoring of power without altering the characteristics of the transmission line.

We manufacture a complete line of directional couplers including combiners, dividers, broadwall directional couplers, dual arm directional couplers, loop couplers, power samplers, short length, high directivity couplers in rectangular waveguide and double ridge waveguide.

ATM’s supplies waveguide directional couplers, in Waveguide sizes WR650, WR430, WR340, WR284, WR229, WR187, WR159, WR137, WR112, WR102, WR90, WR75, WR62, WR51, WR42, WR34, WR28, WR28 and WR22 covering Frequency Bands from 1.12-50.0GHz.

We also manufacture Double Ridge Waveguide size from WRD200, WRD250, WRD350, WRD475, WRD580, WRD650, WRD750 and WRD180.

Basic Types of Waveguide Directional Couplers:

Combiners / Dividers 3dB Hybrid - Small size, full bandwidth
Broadwall Directional Couplers - Multi-hole couplers for full frequency ranges
Dual-Arm Multi-Hole Directional Couplers - Contains a second coupling output with full frequency ranges
Cross Guide Directional Couplers - Covering a wide frequency range in either brass or aluminum
Cross Guide Dual Arm Directional Couplers - Dual arm couplers with 2 waveguide and 2 coaxial ports
Loop Couplers - Ideal for high power sensing, brass or aluminum
Double Ridge Loop Couplers - High power sensing, double ridge waveguide applications
Power Sampler Couplers - Sample power in the main line of waveguide systems
Double Ridge Power Samplers - Sample power in main line of double ridge systems
Short Length, High Directivity Couplers - Short insertion lengths with high directivity
