Silicon-germanium 24 GHz radar transceiver MMIC operates from 24.0 GHz to 24.25 GHz for Doppler and FMCW radar functions. The 3.3 V device integrates a low phase-noise VCO, temperature-compensated tuning source, homodyne quadrature receiver, LNA, and frequency divider. The transmitter provides 2 dBm to 10 dBm output power, while the receiver provides 20 dB typical voltage conversion gain and 10 dB typical single-sideband noise figure. It is housed in a 16-pin leadless RoHS-compliant TSNP-16-9 plastic package and is rated for -40 °C to 85 °C ambient operation.
