Abstract :
A balanced W-band mixer has been developed which integrates a low-loss printed-probe hybrid with fin-line diode mounts on a single substrate. This E-plane approach features production economy, effective shielding, high ( > 400) unloaded Q, light dielectric loading, and simple waveguide interfaces. With the LO fixed at 95 GHz, the measured conversion loss of the mixer is 7.8+-0.7 dB across the RF band of 92-98 GHz.
