Overview

This document describes the implementation of the NXP BGU7003 wideband low noise amplifier (LNA) in 400 MHz and 900 MHz frequency bands, specifically for E-metering applications. It provides comprehensive circuit schematics, bill of materials (BOM), and evaluation board layouts. The design is optimized for low power consumption and high sensitivity, featuring a noise figure below 1.2 dB and gain greater than 15 dB. Included are Agilent ADS simulation results and measured performance data regarding return loss, gain flatness, and stability across a 3.3 V to 3.7 V operating range.

Use Cases

  • E-metering (smart meters)
  • Mobile phones
  • Personal Digital Assistants (PDA)
  • Personal Navigation Devices (PND)
  • Remote controllers
