In this study, a miniature and high performance RF front-end module based on liquid crystal polymer (LCP) substrate is presented. The module consists of microstrip low pass filter (LPF) and low noise amplifier (LNA). The LPF with high rejection is directly fabricated on the LCP substrate, and LNA is mounted on the surface of LCP substrate cavity. The novelty of the proposed module is that it can remain well performance at different curvature. Good results have been achieved with noise figure less than 1dB and signal gain better than 18dB, which indicates that the module will have a great development prospect in the flexible circuit application.
