What is AN643 Lna about?

This application note details the impedance matching of the RX differential low noise amplifier (LNA) for the Si446x/Si4362 RFIC family, aiming to match the LNA input to a 50 Ω antenna source and provide a single-ended-to-differential conversion. It outlines two matching network topologies: a three-element highpass filter and a four-element network for optimal performance, with specific component values provided in summary tables. The document also includes a matching procedure based on measured differentia
