The IC is an integrated transceiver circuit for the 60 GHz ISM band operating in the frequency range of 58.3 GHz - 63.9 GHz. It includes a low-noise-amplifier (LNA) with gain control, quadrature mixers, poly-phase filter, a power amplifier (PA) with gain control, Voltage Controlled Oscillator with digital band switching and divide-by-32 circuit. The output power of the transmitter can be controlled by pwr0 and pwr1 inputs. The IC is fabricated in SiGe BiCMOS technology by using the bipolar part and the CMOS part [1].


The main use of the transceiver IC is in radar systems for the ISM band from 57 GHz to 64 GHz. FMCW is the preferred radar principle to be used.
