Research on the Digital Millimeter Wave MPM

Microwave power module (MPM) is a novel power device which proposed by Advisory Group on Electronic Devices (AGED). This device can well meet the requirement of radar, electronic warfare and similar systems. The system composition and key technology of a digital MPM are introduced in this paper. The advantages and disadvantages of the independent control mode as well as centralized control mode which can be used in the module are analyzed. The digital design principle of the module are discussed, including the key components such as digital high voltage power supply, digital amplitude-phase control, digital control and protection system. The composition, interface, timing control, voltage regulator control and the realized software of the control and protection system are described in detail. Finally, the designed MPM is tested, the result shows that the output power, envelope and bandwidth can meet the requirement of design specification.
