DC114: Directional Coupler for R-26 Waveguide


DC114 is a miniature directional coupler intended for sampling incident or reflected waves in high-power 2450 MHz industrial applications using R-26 rectangular waveguide.

The coupler is fixed to the waveguide with six M3 or similar-diameter screws after machining of appropriate holes in the broad waveguide wall.

Simple reversing the coupler causes it to sample the wave propagating in the opposite direction.

Frequency range 2425 2475 MHz
Coupling factor -60 dB 1 dB standard
-50 dB 1dB available on special order
-70 dB 1dB available on special order
Directivity 25 dB min
Output connector N-F (SMA-F available upon request)
VSWR (N, SMA) 1.25 max
Waveguide of destination R-26 (86.36 mm x 43.18 mm, wall thickness 2 mm)
