AN11086: BGU7003 LNA Application for GPS L2 Band
Application note for the NXP BGU7003 LNA optimized for the GPS L2 band (1.227 GHz), featuring circuit simulations, schematics, BOM, and performance test results.
Overview
This application note provides design guidelines and performance analysis for the NXP BGU7003, a wideband low noise amplifier (LNA) housed in a SOT891 package, specifically tuned for the GPS L2 frequency band at 1.227 GHz. The document includes detailed ADS circuit simulations, an application schematic, PCB layout information, and a comprehensive Bill of Materials (BOM) using parts from Murata, Coilcraft, and Panasonic. It characterizes the evaluation board (EVB) performance, reporting typical results such as 16.4 dB power gain, 1.01 dB noise figure, and +11.15 dBm output IP3 at a 2.5 V supply. The note also discusses the device's logic-controlled enable function and switching times.
