BGT24MTR11E6327XUMA1

Overview

The BGT24MTR11E6327XUMA1 is a fully integrated Silicon Germanium (SiGe:C) monolithic microwave integrated circuit (MMIC) designed for 24 GHz ISM band radar applications. It features one transmitter and one receiver channel, operating within a frequency range of 24 GHz to 26 GHz. The device includes a low phase noise voltage-controlled oscillator (VCO), a switchable prescaler with 1.5 GHz and 23 kHz outputs, and on-chip power and temperature sensors. It operates on a supply voltage between 3.135 V and 3.465 V, delivering an output power of 11 dBm. Current consumption is 150 mA for both transmission and reception. The component supports SPI interface control and functions reliably across a temperature range of -40°C to +105°C.

Feature Summary

• Fully integrated SiGe:C MMIC architecture providing significant board space savings compared to discrete components
• Includes on-chip low phase noise VCO and switchable prescaler for precise signal generation
• Integrated power and temperature sensors enable real-time monitoring and system protection
• Utilizes RC polyphase filters to generate local oscillator quadrature phases for accurate IQ demodulation

Applications

• Short-range radar systems in the 24 GHz ISM band
• Motion detection and presence sensing modules
• Automotive parking assistance and collision avoidance sensors
• Industrial automation proximity sensing

Procurement Notes

Verify the specific suffix E6327XUMA1 against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly from official documentation before integration. Ensure that the obsolete lifecycle status does not conflict with long-term production requirements. Cross-reference pinout diagrams with PCB layout tools to prevent interface mismatches during design-in.

Selection Notes

Select this component when a single-transmitter, single-receiver configuration is sufficient for the application. Consider the 32-pin QFN package dimensions for thermal management and footprint constraints. Evaluate the need for SPI control versus analog-only operation based on system complexity. Compare performance metrics such as output power and sensitivity against alternative devices if higher gain or different frequency ranges are required.

Part Context

This device belongs to the Infineon BGT24Mxx series of silicon germanium MMICs, which are recognized as highly integrated solutions for 24 GHz radar markets. The series includes variants like the BGT24LTR11N16E6327XTSA1, which offers a different pin count and package style. These components share common technological foundations, utilizing 0.18μm SiGe:C processes with a 200 GHz cutoff frequency to ensure high performance in compact form factors.

Replacement Considerations

The BGT24MTR11E6327XUMA1 is listed as obsolete. Potential replacements include other members of the BGT24Mxx family, such as the BGT24LTR11N16E6327XTSA1, though pinouts and packages differ. Verify functional equivalence and interface compatibility carefully when substituting obsolete parts.
