Abstract: This paper introduces the key elements of the design of the three frequency common tower network of all solid state medium wave broadcasting transmitter - premodulation network and blocking network, and introduces the design idea of the triple frequency common tower in this platform. At the same time, it introduces the superiority of adopting the band-pass coupled cooperative matching network.

Key words: Triple frequency common tower; premodulation network; blocking network; apparent power; bandpass coupling
