A 1.7 to 2.7 GHz Transmission-line GaN HEMT Power Amplifier for Wireless Applications

摘要

A low-cost and efficient solution for a broadband transmission-line GaN HEMT power amplifier, based on a 5 W Nitronex NPTB00004 device in a plastic package, is analyzed and described. This power amplifier can be used in various wireless applications covering simultaneously different communication standards such as DCS1800, PCS1900, CDMA2000, W-CDMA or LTE. The theoretical analysis is based on a simple analytical estimation of the parameters of the input lossy matching circuit and nominal output resistance with further computer optimization of the circuit parameters of the entire power amplifier schematic.
