Abstract
Using 0.3 micrometer gate length GaAs/AlGaAs HEMTs, we have designed and realized a single-chip receiver including one 4 bit 360 deg. phase shifter, two low-noise 35 GHz amplifiers, and one low-power Gb/s digital interface circuit. Desired functions have been measured on-wafer. 16 phase-shifting curves have been obtained with a' maximum deviation of 7.5 deg.. The total gain of the millimeterwave channel is similar 7 dB with a phase-dependent deviation of <1.3 dB. The input and the output matching are better than minus 12 dB. The chip area is 4x2.5 sqmm . The dc power consumption is less than 250 mW.
