 click here to view PDF: Rectangular Waveguide Loop Couplers
Space Machine custom fabricates a standard product line of loop couplers covering waveguide sizes WR62 through 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.
