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.
