Abstract :
The design and experimental performance of a broadband (18-26.5 GHz) single balanced mixer, polar discriminator and related components fabricated in microstrip on 0.010-inch thick gold plated sapphire is described. Typical conversion loss of 7.5 dB with a maximum of 8.5 dB at the top of the band was achieved in the mixer. The output polar angle of the discriminator is linear within ±15° with an input signal level of -14 dBm. Full utilization of planar techniques is made that could also be applicable for frequencies up to and above 60 GHz.
