AN11014: BGX7100 Evaluation Board Application Note
Application note for the NXP BGX7100 I/Q modulator evaluation board, featuring schematics, BOM, PCB layout, and performance data for wireless base station applications.
Overview
This application note describes the design and performance of the evaluation board (EVB) for the NXP BGX7100, a high-linearity I/Q modulator. The document provides detailed circuit schematics, two Local Oscillator (LO) configuration options (differential and single-ended), and a complete bill of materials. It includes PCB layout specifications for a four-layer FR4 board and technical performance data, including voltage gain, input/output matching, and current consumption characteristics. The BGX7100 is designed for base station applications, offering 1.5 dB typical voltage gain and 27 dBm typical output IP3.
Use Cases
- Wireless infrastructure RF design
- RF transmitter performance evaluation
- I/Q modulation testing
- Base station transceiver development
