Abstract :
The microwave power module (MPM) is described. This miniature radio frequency (RF) power amplifier combines a low-noise high-gain monolithic microwave integrated circuit (MMIC) solid-state amplifier (SSA) driver with a high-efficiency reduced-gain vacuum power booster helix traveling-wave tube (TWT) and integrated power conditioner (IPC). Progress on the development of 100-200-W power booster TWTs and MPMs covering the 2-40-GHz frequency range is discussed, giving examples of demonstrated RF performance. MPM advantages are contrasted to conventional TWTA and SSPA approaches, along with a discussion of various MPM-based transmitters for architectures. Numerous applications of MPM transmitters for radar, electronic countermeasure, communications, and space have been identified with widespread implementation expected to take place in the near future
