Signal after high frequency power amplifier amplification can satisfy the requirements of the antenna to transmit power, with enough power to launch out, distant receiver receives in a reliable way. High frequency power amplifier according to the working frequency points, high frequency power amplifier can be divided into narrowband and broadband high frequency power amplifier, narrowband high frequency power amplifier is usually to LC resonant network as a load, also called resonance power amplifier, high frequency signal is usually a narrowband signal, narrowband signal refers to the signal bandwidth is far less than its center frequency, such as the bandwidth of the medium wave radio station to 10 KHZ, if the center frequency of 1000 KHZ, its bandwidth is far less than its center frequency, the signal is narrow band signal. Narrowband signal is similar to the single frequency sine signal characteristics, resonant circuit filter can be used. Broadband power amplifier is based on a transmission line transformer load, also known as the resonance power amplifier, difference in narrow band power amplifier and broadband power amplifier working frequency can be changed in a very wide range and don39。t have to be tuned, but I don39。t have filtering capability. Key words: High frequency resonance power amplifier, power amplifier, narrow band signal. 目 錄概述及基本原理 41方案及各部分設(shè)計(jì)原理分析 6 6 6 7 7 8 9 9 15 173單元電路的設(shè)計(jì) 18 18 18 19 21 21 234電路仿真與結(jié)果分析 26【參考文獻(xiàn)】 27高頻功率放大器設(shè)計(jì)前言高頻功率放大器用于發(fā)射機(jī)的末級(jí)，作用是將高頻已調(diào)波信號(hào)進(jìn)行功率放大，以滿足發(fā)送
