Custom 24GHz Radar Module | Infineon BGT24 + STM32 Processing | PCB Design & Engineering
Description
Custom-designed 24GHz radar sensor module featuring Infineon's BGT24-series radar transceiver IC with STM32 microcontroller-based signal processing. This compact circular PCB design integrates the complete RF front-end with dual SMA connectors for TX/RX antenna interfacing, I2C communication (SCL/SDA), V_tune frequency control, and on-board IF signal conditioning (IFI/IFQ).
The multi-layer board incorporates careful RF layout practices including controlled impedance traces, extensive ground stitching vias, and shielded component placement for optimal 24GHz performance. Key header breakouts provide access to GND, 5V, TX_EN, V_DAC, VCC_DIV, and EN control signals — enabling seamless integration into larger embedded systems.
