90年代以来,各地人民广播电台纷纷引进全固态机取代电子管中波发射机。全固态机的应用标志着中波发送设备的更新换代,它替换了效率低、指标差、停播率高的电子管中波发射机。但是,应用全固态中波发射机,使用了大量的微处理器件和半导体器件,功放应用IRFP350场效应管。与过去的电子管发 Since the 1990s, people’s radio stations all over the country have introduced all-solid-state machines instead of tube-wave transmitters. The application of the all-solid-state machine marks the upgrading of medium wave sending equipment, which replaces the tube medium wave transmitter with low efficiency, poor index and high stop-down rate. However, the application of all-solid-state wave transmitter, using a large number of microprocessors and semiconductor devices, power amplifier applications IRFP350 FET. With the past tube hair
