Abstract
In this article a high power (320 watt), high efficiency (greater than 56 %) LDMOS based power amplifier configuration is proposed. Proposed compact class-AB amplifier is designed using non-linear model of MRF8P29300, targeting S-band. Along with optimization using ADS, hybrid couplers are used to improve the performance of proposed amplifier, providing output power of 56 dBm. Other than design details, paper also present electromagnetic and thermal analysis for better understanding of amplifier characteristics. Moreover, measured results indicate that proposed amplifier achieved 14dB gain, gain flatness <0.7dB and input/output return loss <-12dB; which make proposed amplifier worthy and prospective candidate for surveillance and tracking radars.
