Abstract
This paper introduces the design and realization of a UHF-band 150 W amplifier.There are many kinds of transistor,so choosing appropriate transistor and matching circuit are important for amplifier design.In the design,in order to implement miniature and high efficiency,the intermediate-power high-efficiency wideband transmitter and line transformer are used to perform resistance matc-hing,and 3 dB bridge and balun line are used to perform dividing and combining.The miniature design is implemented for coupler and structure.A UHF-band 150 W amplifier is designed and debugged,the test results show that the efficiency surpasses 45%,the harmoni-zation is higher than 20 dBc,and the dimensions are less than 241 mm×106 mm×31 mm.关键词
