广西广播电视厅于86年改制成功的120KW并馈PDM发射机,投入运行七年多,取得了显著的社会效益和经济效益。 该机87年通过省级技术鉴定,全部技术指标达到部定甲级机标准。该机由于采用金属陶瓷四极管、集成电路脉持头,高频末级利用四次谐波提高板极效率和半导体阻尼管装置等新技术,使整机效率达到65％以上,残波辐射优于-80dB。该机运行稳定、音质优美,电声指标
Guangxi Radio and Television Hall in the successful restructuring of the 120KW PDM transmitter and fed into operation for more than seven years and achieved significant social and economic benefits. The aircraft passed the provincial technical appraisal in 87 years and all the technical indicators have reached the standard of Class A fixed unit. The machine due to the use of cermet, integrated circuit pulse head, the use of the fourth harmonic high-frequency high-end plate efficiency and semiconductor damping tube device and other new technologies, the machine efficiency of 65% or more, residual wave radiation Better than -80dB. The machine is stable, beautiful sound quality, electro-acoustic indicators
