Couplers

Branch Guide Couplers

Space Machine custom fabricates a standard product line of branch guide couplers covering waveguide sizes WR62 thru WR284.  Inherently full band coupling is not very flat, but coupling over 25% bandwidth is held to ±0.5dB.  Directivity is 20dB minimum.  Additional sizes & configurations are available upon request.

Cross Guide Couplers

Space Machine custom fabricates a standard product line of cross guide couplers covering waveguide sizes WR28 thru WR284. Coupling variation is typically + 1dB over the full waveguide band. Directivity is 20dB minimum. Additional sizes and configurations are available upon request.
