常见的高频功率模块,如三菱株式会社出品的M57704L、M57719等其性能及应用已为大家所熟悉。这些高频组合器件一般采用“CaAs FET”或数个晶体管合成工艺与外围电路组成推挽或末级单管电路,输出145～175MHz或450～470MHz窄带信号,个别品种还带有推动级,故输入信号电平可做得较低。在这里将要介绍的是国内电子界较为鲜见的适用于1.8～175MHz宽带的MC7210及MC5792高增益功率组件,希望通过介绍,能被国内热衷于1.8～175MHz业余频段及有幸拥有29.6MHz频段“PASS”的“火腿们”(HAM)及各界读者所了解并开发应用。
Common high-frequency power modules, such as MITSUBISHI Co., Ltd. produced M57704L, M57719 other properties and applications have become familiar to everyone. These high-frequency combination of devices generally use “CaAs FET” or several transistor synthesis process and the peripheral circuit composed of push-pull or final-stage single-tube circuit, output 145 ~ 175MHz or 450 ~ 470MHz narrowband signal, The input signal level can be made low. Will introduce here is relatively rare in the domestic electronics industry for 1.8 ~ 175MHz broadband MC7210 and MC5792 high gain power components, hope that through introduction, can be domestic enthusiastic 1.8 ~ 175MHz amateur band and fortunate to have 29.6MHz band “PASS ”HAM" (HAM) and readers from all walks of life to understand and develop applications.
