Integrated Design of Multifunctional Solid-state Transmitter

A multifunctional solid-state transmitter is introduced in this paper.A few issues are discussed,including multifunctional requirements of the solid-state transmitter,different transmitter schemes,composition and principle of the solid-state transmitter modules,and key technical difficulties of the transmitter.Transmitting low sidelobe of active phased array radar antenna is a notable feature of the transmitter.Transmitting low sidelobe can be realized by using distributed,amplitude weighted transmitter modules.In order to integrate the functions,a series of engineering problems that should be solved in the process of the transmitter development are discussed in detail.Satisfying experimental results are given in the end.
