Abstract :
A waveguide and planar self oscillating mixer using the Quantum Well Injection Transit Time (QWITT) diode have been tested at X-band. The waveguide mixer circuit can either be tuned to have a narrow band conversion gain of about 10 dB or broad band conversion loss of 4 dB. The planar mixer circuit exhibits a narrow band conversion gain of 4 dB or a broad band conversion loss of 8 dB. These are the first experimental results showing conversion gain from a self oscillating mixer using a quantum well diode.
