An all-solid-state multiplexed microwave power radar transmitter

Abstract

The invention relates to an all-solid multi-channel synthetic microwave-power radar transmitter which comprises a power divider, at least two power amplification modules, a synthesizer and a control motherboard. An input signal of the transmitter is uniformly divided into multiple channels of signals with equal amplitudes and identical phases by the power divider, the multiple channels of signals are inputted into the various power amplification modules, and each power amplification module receives one signal; the power amplification modules amplify the received signals, and amplified signals are transmitted to the synthesizer; power of the multiple channels of amplified signals is synthesized by the synthesizer, and synthesized signals are outputted by the transmitter; the various power amplification modules work under the control of the control motherboard. The all-solid multi-channel synthetic microwave-power radar transmitter has the advantages that the synthesis efficiency can be effectively improved under the condition that the power amplification modules fail, the all-solid multi-channel synthetic microwave-power radar transmitter is all-solid, has bi-channel amplification and synthesis functions, is compact in structure, is provided with high-efficiency GaN power amplifiers and is adaptive to failures, design requirements can be met, and the like.

Description

technical field [0001] The invention relates to radar transmitting technology, in particular to an all-solid-state multi-channel synthetic microwave power radar transmitter. Background technique [0002] A certain type of radar transmitter requires an output continuous wave power of more than 200W, and at the same time meet the requirements of compact structure, high efficiency, high spectrum purity, high reliability, and various adaptive protection functions. [0003] At present, the output power of a single tube of some vacuum devices can meet the requirements, but its volume is large and its reliability is not high. The output power of the traditional single-tube solid-state power amplifier is too small to meet the design requirements. Contents of the invention [0004] In view of the defects or deficiencies in the above existing technical solutions, the purpose of the present invention is to provide an all-solid-state multiplexed microwave power radar transmitter.
