Ka-band 2W and 4W MMIC Power Amplifiers In 7脳7mm Low-cost SMT Package

摘要

This paper describes the design and usage of 2W and 4W SMT packaged high power amplifiers (HPA) suitable for low cost sub mm-wave applications. The development of PHEMT HPA MMICs are described. The designed 2W and 4W power amplifiers exhibit 20 dB of small signal gain, 33dBm and 35dBm 1dB gain compression output power respectively in between 24 and 31GHz frequency range. Those MMIC PAs were assembled in 7脳7mm low cost SMT packages, and obtained nearly identical RF performances as the die parts.
