BGT24MTR12E6327XUMA1

Overview

The BGT24MTR12E6327XUMA1 is a silicon-germanium (SiGe:C) monolithic microwave integrated circuit (MMIC) radar transceiver operating in the 24 GHz to 24.25 GHz ISM band. It features one transmitter and two receivers, delivering an output power of 11 dBm and a gain of 26 dB. The device operates on a supply voltage ranging from 3.135 V to 3.465 V, with typical transmit and receive currents of 210 mA each. Manufactured using a 0.18 μm SiGe:C process with a 200 GHz cutoff frequency, it utilizes RC polyphase filters for local oscillator quadrature phase generation. The component is housed in a 32-pin VQFN package and supports SPI interface control.

Feature Summary

• Integrates single-transmitter dual-receiver architecture within a compact MMIC design
• Utilizes 0.18μm SiGe:C technology for high-frequency performance up to 200 GHz cutoff
• Incorporates RC polyphase filters to generate precise LO quadrature phases
• Provides significant board space savings compared to discrete component solutions

Applications

• Consumer IoT radar sensing applications
• Short-range motion detection systems
• Presence detection modules
• Automotive proximity sensors

Procurement Notes

Verify current availability status as this specific part number may be discontinued or subject to limited distribution channels. Confirm that the 32-pin VQFN package dimensions and thermal requirements align with your PCB layout constraints. Ensure compatibility with the required SPI communication protocol for configuration. Check for any alternative lead-free or RoHS compliance documentation if required by your manufacturing standards. Validate that the operating temperature range meets your environmental specifications.

Selection Notes

Select this component when a dual-receiver configuration is necessary for angle estimation or improved signal processing capabilities within the 24 GHz ISM band. It is suitable for designs requiring high integration to minimize footprint, offering approximately 30% space reduction versus discrete alternatives. Consider the 210 mA current consumption per channel for power budget calculations. This device is appropriate for applications needing moderate output power and gain without external amplifiers.

Part Context

This device belongs to the Infineon BGT24Mxx series of SiGe MMICs, which are recognized as highly integrated 24 GHz radar transceivers. The series includes variants such as the BGT24MTR11 (single Tx, single Rx) and the BGT24LTR11N16E6327XTSA1. These components share common underlying technologies, including the 0.18 μm SiGe:C process and RC polyphase filter structures, designed to simplify radar system development for consumer and IoT markets.

Replacement Considerations

The BGT24MTR11E6327XUMA1 serves as a functional substitute for single-receiver applications. For dual-receiver needs, verify if newer revisions or similar family members are available, as this specific part number is listed as discontinued in some distributor catalogs.
