Research on Photovoltaic Amplifier Circuit based on Filter Module

The amplifier filter module is the compulsory module of the RF front-end circuit, which can realize the function of signal amplification and selection in the RF system. The quality of amplifying filter components directly affects the performance and size of the whole electronic system. In this paper, photovoltaic amplifying and filtering features are studied, and a new silicon-based integration scheme based on MEMS technology is explored to realize the miniaturization and lightness of photovoltaic amplifying and filtering components, thus breaking through the application bottleneck of photovoltaic RF system in small platform equipment. This paper studies the photovoltaic amplifying filter module composed of the bandpass filter and low noise amplifier. Considering the performance, size, technology and innovation factors, based on the new design scheme combining MEMS process and substrate integrated waveguide (SIW) structure, the module and the critical circuit of the module – bandpass filter are studied.
