Abstract :
A C-band phase and gain control MMIC (monolithic microwave integrated circuit) has demonstrated a maximum gain of 31+or-2 dB with 20 dB of gain control from 5-6 GHz. The 6-bit phase shifter has an RMS phase error of less than 3.1 degrees . Lumped elements result in a small (5.4-mm*2.15-mm), low-cost MMIC. The variable-gain-amplifier features a segmented dual-gate FET. Sensitivity analysis was used to select a phase-bit design with minimum sensitivity to process variations.<>
