Abstract
A novel quasi-optical all-planar frequency doubler that could provide an alternative approach to conventional waveguide circuits for millimeter- and submillimeter-wave signal generation is presented. The multiplier uses a quad-bridge diode configuration for inherent isolation between the input and output signals. Two pairs of double-slot antennas with orthogonal polarizations directly couple input and output signals to the diodes, without the need for hybrid couplers required in typical balanced circuits. The integrated quad-bridge-diode/slot-antenna circuit is mounted on a dielectric-filled parabola for coupling to quasi-optical propagation systems. Measurement results for an X to K-band doubler show frequency conversion loss of 6.8 dB at the output frequency of 20.3 GHz.
