BGT24LTR11N16
24GHz to 24.25GHz radar MMIC packed in a 16-pin leadless RoHS compliant TSNP package
BGT24LTR11 is a silicon germanium radar MMIC for signal generation and reception, operating in the 24GHz to 24.25GHz ISM band. It is based on a 24GHz fundamental voltage controlled oscillator (VCO). The device was designed with doppler-radar applications in mind — as it is capable of keeping the transmit signal inside the ISM band without any external PLL — and may also be used in other types of radar such as FMCW or FSK. The device is manufactured in a 0.18 μm SiGe:C technology offering a cutoff frequency of 200GHz. It is packaged in a 16-pin leadless RoHS compliant TSNP package.

PIR vs. Radar – Which technology is right for me?
Passive Infrared (PIR) sensors have traditionally been the technology of choice for motion detection sensors. However, recent developments in radar technology have made radar sensors even smaller and more cost effective – making them a viable alternative to PIR and, in many cases, a preferable solution for motion detection.
The right technology for you depends on the requirements of your application – including cost, functionality and design. To ensure you get the best fit for your application, we have outlined some of the key benefits of radar sensors compared to PIR.
Most importantly, radar sensors can provide much more information than PIR technology. While PIR sensors detect objects based on their heat signature, radar sensors use the Doppler principle. This enables them to detect if an object is moving or stationary as well as to measure the direction and speed at which it is travelling, while covering a greater detection area than PIR sensors. Compared to PIR, they are also hardly affected by ambient conditions such as snow or heat and offer greater flexibility when it comes to design. Besides that, radar sensors can be discretely installed behind walls and other fixtures providing the possibility to install them invisible from the outside. This makes them ideal for applications such as smart home lighting, intelligent street lighting, intruder alarms, automatic doors and screens.
