Low-Noise Mixer in Oversized Microstrip for 5-mm Band (Short Papers)

This short paper summarizes the design and performance of a low-noise 5-mm mixer constructed in oversized microstrip---a new type of transmission line which is superior to microstrip at millimeter wavelengths. Includlng a 5-dB IF contribution, the measured noise figure was 9-10.5 dB over a wide range of LO frequencies and drive levels.
