In order to realize a massive MIMO concept, small size and low power consumption over the wide-band frequency range are challenges for RF frontends module. This paper describes highly integrated frontend module high SHF in 5G. The is designed with 0.15 μm GaAs process assembled on 5 × mm2 QFN package. By employing Doherty amplifier configuration using parasitic output capacitance neutralization technique, it achieves wide band. architecture an attractive solution systems 5G, will contribute 5G deployment. Additionally, use of digital techniques future option beyond 4G (toward 5G), amplifiers them potentially lead reduction consumption. Some prototyped switching-mode also presented.
