An Amplitude-Phase Adjustable Four-Channel Precursor Transmitter Component

An amplitude-phase adjustable four-channel precursor transmitter component was introduced. which was composed of power excitation module and RF amplifier module. The power excitation module mainly realizes voltage conversion and phase/amplitude modulation signal transmission, The microwave RF module mainly realizes four-channel amplification output of microwave signal. The component has a great advantage can keep the amplitude and phase of the four output channels relatively consistent. The precursor transmitter component was fabricated in a single package occupying area of 180mm*80mm*18mm.The weight of the component is 0.6kg. In this paper, the design, principle and test results of the component will be further discussed.
