✦ Synopsis

The successful development of a new four-stage 1-W AlGaAs/InGaAs/GaAs PHEMT MMIC with a temperature-compensating GaAs feedback resistor is reported. It was found that we can signifi-cantly reduce the gain variation in the temperature range between Ϫ40 and 80°C from 7 dB to less than 3 dB by using the temperature-compensating GaAs feedback resistor. It was also found that the use of the GaAs feedback resistor will neither result in a decrease in output power nor a decrease in the PAE of P sat for the temperature compensated power amplifier.

## Abstract In this paper, a Ka‐Band 24‐dBm AlGaAs/InGaAs/GaAs PHEMT MMIC power amplifier is demonstrated. This three‐stage amplifier is designed to fully match for 50Ω input and output impedances. With 4 V and 250‐mA DC bias, we achieve 15‐dB small‐signal gain, 24 dBm P~−1dB~, 24.3% PAE, and bette

## Abstract A Ku‐band power amplifier MMIC has been developed using 0.25‐μm GaAs pHEMT technology. To achieve small chip size and simple drain‐bias connection, a bus‐bar power combiner is used. Also, balanced‐power amplifier topology is used to obtain good input/output return losses. The small‐sign
