A 30-GHz monolithic single balanced mixer with integrated dipole receiving element
Abstract
This paper describes a 30-GHz monolithic low-noise balanced mixer which has been developed using an integrated bow-tie antenna to waveguide transition and low parasitic Mott diodes. The diodes and mixer circuit were developed using MBE material and were fabricated using a plated airbridge technology. Measurements on the diode at dc and RF showed that the zero bias junction capacitance was 0.025 pF and the series resistance was 10 ohm. A mixer conversion loss of 6 dB was measured at 30 GHz with an IF of 1 GHz.
