InnoSenT launches surface-mountable radar motion detector using Infineon 24GHz SiGe transceiver MMIC

InnoSenT GmbH of Donnersdorf, Germany has launched a surface-mountable radar (SMR) motion detector operating in the 24.0-24.25GHz industrial, scientific & medicial (ISM) band that incorporates the latest 24GHz silicon germanium (SiGe)-based transceiver MMIC (BGT24LTR11) from Infineon Technologies AG of Munich, Germany, offering what is claimed to be a unique combination of high functionality, low power consumption and easy-to-install solution.

Compared with passive infrared (PIR) technology, the use of radar in motion detection applications increases accuracy, since it allows a more precise measurement of object detection and provides new capabilities such as the detection of speed and direction of moving objects. Radar is also superior to camera-based systems by allowing detection of the objects while keeping identities anonymous.

Infineon's BGT24LTR11 transceiver MMIC features a fully integrated low-phase-noise voltage-controlled oscillator (VCO) and built-in temperature compensation circuit for VCO stabilization. It also has full ESD protection, Infineon's 200GHz bipolar SiGe: C technology (B7HF200), and a single supply voltage of 3.3V. The SMR module's ultra-compact design (20mm x 15mm x 3mm) eases integration, allowing installation in small spaces. It provides a solution for security applications, home automation, lighting control, intelligent machine control, touch-free switches, and movement detection.

InnoSenT's SMR series comprises three types with different antenna characteristics. In addition to the option of simple motion detection with a corresponding evaluation, it is also possible to determine speed information and the direction of movement to the detected object from the returned data. Infineon's SiGe radar MMIC was designed with Doppler radar applications in mind, which enables additional functionalities. Besides the 24GHz fundamental VCO, it also provides the SMR series with variants for FMCW (frequency-modulated continuous-wave) or FSK (frequency shift keying) operation mode.
