Abstract :
The design and test results for multifunction monolithic microwave ICs (MMICs) for C-band transmit/receive (T/R) modules are presented. This small-signal chip set contains the entire receive path (5 stages of amplification and 10 passive devices) in just three chips. These ICs, fabricated with the multifunctional self-aligned gate (MSAG) process, demonstrate a high level of integration, excellent performance. and a good yield. The variable-gain low-noise amplifier has a 30+or-1-dB gain, and a 2.5-dB noise figure, the phase shifter single-pole, double-throw (SPDT) switch has an 8+or-1-dB loss, and the buffer amplifier has a 6.5+or-0.2-dB gain and a 3.5-dB noise figure. Average yield for these circuits was 40% or better.<>
