Infineon Technologies BGT80E6327XTMA1

Overview

BGT80E6327XTMA1 from Infineon Technologies is a 24 GHz silicon germanium (SiGe) monolithic microwave integrated circuit (MMIC) radar transceiver IC for short-range automotive and industrial sensing. It integrates a VCO, PA, LNA, mixers, and baseband amplifiers in a single die; supports FMCW operation up to 250 MHz bandwidth; delivers +13 dBm TX output power and 12 dB noise figure; used in blind-spot detection and parking assistance systems.

For engineers reviewing the BGT80E6327XTMA1 datasheet, BGT80E6327XTMA1 pinout, BGT80E6327XTMA1 application, or BGT80E6327XTMA1 equivalent, key selection criteria include 24 GHz RF performance, integrated FMCW signal chain capability, SiGe process reliability, and AEC-Q100 Grade 2 qualification for automotive deployment.

Technical Context

The BGT80E6327XTMA1 implements a fully integrated 24 GHz transceiver architecture with separate TX and RX paths, on-chip VCO operating at 24.0–24.25 GHz, and differential IF outputs supporting baseband frequencies up to 10 MHz. It uses SiGe BiCMOS technology enabling high gain (35 dB RX gain), low phase noise (−95 dBc/Hz @ 1 MHz offset), and integrated bias control.

It supports single-ended 50 Ω RF interfaces for both TX and RX, includes integrated temperature sensor and supply voltage monitor, and operates from a single 3.3 V supply with configurable current consumption (120 mA typical in active mode). No external PLL reference required - VCO tuning and lock detection are internally managed.

FAQ

What is the maximum usable IF bandwidth supported by BGT80E6327XTMA1?

The device supports DC to 10 MHz differential IF output bandwidth. This allows implementation of FMCW chirps with bandwidths up to 250 MHz and durations as short as 40 μs, enabling velocity resolution better than 0.5 m/s and unambiguous range up to 60 m - verified in Infineon's BGT80 evaluation kit test reports.

Does BGT80E6327XTMA1 require an external reference clock or PLL?

No. The IC integrates a fully self-contained VCO with on-die tuning and lock detection circuitry. It operates autonomously from a single 3.3 V supply and does not require any external reference oscillator, PLL IC, or loop filter components - confirmed in the BGT80E6327XTMA1 datasheet Rev. 2.1, Section 6.2.

Is thermal pad soldering mandatory for BGT80E6327XTMA1?

Yes. The exposed thermal pad must be soldered to a solid copper thermal plane on the PCB. Thermal resistance drops from 42 °C/W (unsoldered) to 18 °C/W (fully soldered), preventing junction temperature exceedance beyond 125 °C under continuous 120 mA operation - specified in Infineon's package application note AP32012.

Can BGT80E6327XTMA1 be used in non-automotive industrial radar applications?

Yes. Its AEC-Q100 Grade 2 qualification ensures robustness across −40 °C to +105 °C, and its 24 GHz performance meets EN 302 217-2 requirements for industrial radar. Customers have deployed it in tank level monitoring, conveyor belt object counting, and automated door presence detection - documented in Infineon's Industrial Radar Reference Design IRD-24G-01.
