摘要：
Aiming at parasitic effect physical design of the power amplifier, according to the load-pull result of input and output impedance by the conjugate match, a wideband high efficiency method of power amplifier was proposed basing on the momentum technology and load-pull method in this paper after using the ADS software. To realize high efficiency, matching circuit is applied to the amplifier to reduce the chip size, which are changed into corresponding momentum components and re-used in schematic design with well improvement design accuracy are designed by the conjugate match method basing on the analysis of unconditional stability, as well as to realize the optimum impedances over a wide bandwidth for high efficiency at each stage. The simulation results showed that the new method could get the optimal output within three iterations, which verified that the new method is a practical and efficient in power amplifier design.
