Abstract :
The design and performance of a MIC 26.5-40 GHz mixer is described. The mixer utilizes GaAs beam lead Schottky barrier diodes with a cutoff frequency of 750 GHz in a balanced arrangement with slot-line and coplanar waveguide. Conversion loss for the full waveguide band is 7.6 ± 0.5 dB with + 6 dBm LO drive. VSWRs are less than 2:1 for the RF port and 3.4:1 for the LO port. The mixer exhibits excellent LO to RF isolation, typically 25 dB and handles IF frequencies up to 8 GHz.
