采用微带混合集成电路可以在P波段制作成体积小,效率高,适用于机载设备和小型电台的多级功率放大器。本文描述了作者为某工程机载设备研制成的350MHZ三级功率放大器的设计。输出功率5W增益>20dB;总效率>40％:体积190×40。
The use of microstrip hybrid integrated circuits in the P band can be made into small, high efficiency, suitable for airborne equipment and small radio multi-stage power amplifier. This article describes the design of a 350 MHz three-stage power amplifier developed by the author for an engineering airborne equipment. Output power 5W Gain> 20dB; total efficiency> 40%: Volume 190 × 40.
