The BGT24ATR11 is a SiGe MMIC transceiver for signal generation and reception, operating in the 24 GHz ISM band from 24 to 24.25 GHz. The Tx side of the transceiver has a 24 GHz VXO and delivers 11 dBm of signal power to the antenna. It has an auxiliary LO output that is available to provide LO signal to separate receiver components.
On the Rx side, it has an integrated low phase noise voltage controlled oscillator and switchable frequency prescalers with output frequencies of 1.5 GHz and 23 kHz. The Transceiver LNA provides a low noise figure and has an RC polyphase filter (PPF) that is used for LO quadrature phase generation of the homodyne quadrature downconversion mixer.
The device is controlled via SPI and is manufactured in a 0.18μm SiGe:C technology offering a cutoff frequency of 200 GHz. The MMIC is available in a 32 pin leadless RoHs compliant VQFN package and is ideal for automotive radar applications.
