Abstract
A quasi-optical Schottky receiver based on an integrated planar antenn a-mixer structure has been developed and tested at 335 GHz. The receiv er antenna is based on the quasi-integrated horn antenna with 23 dB di rectivity. At room temperature, the measured DSB antenna-mixer convers ion loss and noise temperature at 335 GHz are 8.5 dB and 1750K, respec tively. This simple and tunerless design has a noise figure within 1 d B of the best tuned room temperature waveguide mixer using a similar p lanar GaAs Schottky diode [1].
