Abstract :
This paper presents the design and characterization of a V-band radiometer MMIC with 0.10 μm GaAs pHEMT technology. The circuit includes a resistive image reject mixer and a ×4 frequency multiplier LO chain. The ×4 frequency multiplier gives higher than 5 dBm output power over 48-56 GHz. The CL (Conversion loss) of the radiometer measured as an average of 8.5 dB with ripple less than 0.4 dB. The circuit also exhibits very good IMR (image rejection ratio) of higher than 30 dB.
