Space Machine offers a range of solutions to help review prototypes and scale up your production waveguides and parts.Our world class manufacturing facility expertise ensures your order is delivered to your exacting specifications.
Rectangular Waveguide Dual Loop Couplers
Space Machine custom fabricates a standard product line of dual loop couplers covering waveguide sizes WR62 thru WR430. These loop couplers are ideally suited for 25% bandwidths with coupling variation of ± 0.5dB. Over the full waveguide band, coupling variation is + 2.5dB. Directivity is 18dB minimum.
Main arm VSWR is 1.08:1 and secondary arm VSWR is 1.3:1.
