Introduction

The technical world is moving, growing, and changing rapidly. Intense market competition creates high-cost pressure, demanding efficiency in every development segment. One effective approach addresses these challenges by integrating multiple applications and services into a single solution. This integration extends beyond the application housing to include selected components such as the microcontroller, voltage regulator, radio frequency components, and antennas. Such integration requires highly integrated products with maximum flexibility. This application note focuses on designs that use multiple sub-GHz frequencies within a single application. It discusses the functions and features of Microchip’s highly integrated Ultra-High Frequency (UHF) transceiver portfolio and explains how to realize a multi-band application using different approaches.
