Features
Radar transceiver for 122 GHz ISM band
Single supply voltage of 3.3V
Fully ESD protected device
Low power consumption 370mW
Integrated low phase noise Push-Push VCO
Receiver with homodyne quadrature mixer
RX and TX patch antennas
QFN-56 leadless plastic package 8x8mm2
Pb-free (RoHS compliant) package
IC is available as bare die as well (without antennas)
Overview
The IC is an integrated transceiver circuit for the 122 GHz ISM-band with antennas. It includes a
low-noise-amplifier (LNA), quadrature mixers, poly-phase filter, Voltage Controlled Oscillator with
digital band switching, divide by 32 circuit and power detector.
The power level can be measured by two power detectors placed between the power amplifier and
TX-output. The RF-signal from oscillator is directed to RX-path via buffer circuits. The RX-signal is
amplified by LNA and converted to baseband in two mixers with qadrature LO. The 120GHz
oscillator has three coarse tuning inputs and one analog fine tuning input. The analog fine tuning
input can be used for CW radar operation with fixed frequency in PLL-mode by using the internal
frequency divider (1/32) or for FMCW-radar.
The IC is fabricated in IHP SG13S SiGe BiCMOS technology.

Applications
