Based on advanced design system （ADS） simulation software platform, by harmonic balance theory, laterally diffused metal oxide semiconductor（LDMOS） microwave power amplifier was designed. In order to achieve the impedance matching of the input and output ports, the load-pull and source-pull technology were employed by selecting the power transistor MW6S004N of Freescale company, and schematic-layout co-simulation method was used to achieve the power amplifier design. It showed that the load-pull and source-pull impedance matching techniques could reduce the cost and design cycle, the harmonic balance method could accelerate the simulation speed, and the cosimulation method could improve the accuracy of the simulation results.
