Ultra-wideband Reconfigurable Low-noise Amplifier Based on 5G Communication

For 5G communication, both sub-6G and millimeter wave bands have their own advantages, while low-noise amplifier (LNA) is an essential component of the first stage receiving system, its performance plays a crucial role in overall system. Therefore, LNAs applicable to ultra-wideband reconfigurable can make full use high low frequency bands, which one research focuses communication development at this stage. In paper introduces amplifiers methods achieving reconfigurability, explaining advantages limitations each method separately.
