The IC is an integrated transceiver circuit for the 24-GHz ISM band in the frequency range 24.0 GHz – 24.25 GHz. It includes a low-noise amplifier (LNA) with gain control, quadrature mixers, a poly-phase filter, a voltage controlled oscillator with band switching, and a divide-by-8 circuit. The receiver can be powered down if PWR_RX pin is supplied with 0 V. The gain of the receiver can be digitally controlled by Vct pin: Vct = 3.3 V sets the receiver in high gain mode, Vct = 0 V sets the receiver in low gain mode. The output power of the transmitter can be controlled by the pwr1 input. The IC is fabricated in SiGe BiCMOS technology by using the bipolar part and the CMOS part. Beside the TRXˍ024ˍ007, an IC variant with a divider division ratio of 1:32 is available as TRXˍ024ˍ006.
The TRXˍ024ˍ007 can be used in in radar systems and wireless communication systems for the ISM band from 24.0 GHz to 24.25 GHz and for UWB applications between 23 GHz and 26 GHz.
