摘　　要：随着城市的发展和规模的扩大,大连广播电视发射台承担的调频广播发射任务从4套增加到了12套,为了有效节约发射塔上天线段占用空间,提高新增调频广播节目的发射效果,大连广播电视发射台通过自主研发调频广播十二工器,满足12个调频频率通过一副高增益天线发射的使用需求。通过合理化设计调频十二工器的滤波器、3dB耦合器,调频广播十二工器满足了设计指标要求;同时采用滑动底座的设计及应用,对十二工器的安装、调试起到了便利作用。With the development and expansion of cities,the FM transmission tasks undertaken by Dalian Radio and Television Transmission Station have increased from 4 sets to 12 sets.To save space on the tower and improve the transmission effect of new FM programs,Dalian Radio and Television Transmission Station have independently developed a 12-port multiplexer to meet the usage needs of transmitting 12 FM programs through a high gain antenna.By rationalizing the design of filters and 3dB couplers for the 12-port multiplexer,the 12-port multiplexer meets the design specifications requirements.At the same time,the design and application of a sliding base have played a convenient role in the installation and debugging of the multiplexer.
