Overview

This application note describes the design, simulation, and implementation of a Low Noise Amplifier (LNA) optimized for the 433 MHz ISM band using the NXP BFU530 wideband transistor. The design targets battery-powered equipment with a 3.6V nominal supply and 10mA current consumption, aiming for a noise figure below 1.3 dB and approximately 15 dB of gain. The document details the DC bias setup, input/output matching, and stability analysis using Advanced Design System (ADS) simulation models. It also provides guidance on implementation using universal PCBs and evaluation of RF parameters across temperature ranges.
