A highly compact and efficient dual-mode power divider suitable for multi-level (4(N)) beam-forming networks is presented. Circular waveguide dual polarization is accomplished by using a symmetric 4:1 turnstile-like topology and strategic cavity resonance suppressors to achieve more than 20% bandwidth operation with a theoretical 35 dB cross-polar discrimination. Experimental verification for a Ku-band (10.5-13 GHz) dual-mode four-way power divider is presented, showing a common port return loss better than 20 dB, an input-output isolation (orthogonal modes) better than 30 dB, and an insertion loss around 0.25 dB.
