Abstract

Summary form only given. Northrop Grumman´s ongoing development of microwave power modules (MPMs) provides microwave power at various power levels, frequencies, and bandwidths for a variety of applications including communications, radar, and ECM. The MPM combines an integrated power conditioner (IPC), solid state amplifier (SSA), and traveling wave tube (TWT) within a single module resulting in a small, lightweight package for efficient DC/RF energy conversion. Recent advances in the C-band TWT have resulted in a module efficiency greater than 50% at power levels in excess of 170 W. Performance characteristics of the C-Band MPM and both TWT programs will be presented.
