Abstract
A 36--44 GHz HPA was developed for radio applications with complex modulation schemes which require high linearity.The 3-stage HPA achieves a gain of 17 dB and a P-1dB output power of 26.3 dBm.The HPA demonstrates an output IP3 which is 10 dB higher than P-1dB whereas comparable amplifiers have only 6 dB to 8 dB difference between P-1dB and OIP3.The increased linearity permits compact designs with lower dc power consumption due to the reduction of the necessary HPA output power level.
