In order to meet the needs of multi-function and multi-task for radars, a dual channel hybrid transmitter is proposed, which is based on the parallel operation of vacuum tube and solid state tube. Several design points of this kind of transmitter are introduced, including the design of dual-channel radio frequency link, multifunctional integrated control and protection system, miniaturized broadband traveling-wave tube amplification chain, and solid state amplification chain. According to the application characteristics of this transmitter, the key points of structure and thermal design are briefly introduced and partial simulation results of thermal design are presented.
