A 24-GHz direct-conversion transmitter is proposed for in-cabin radar applications.\nThe proposed RF transmitter consists of an I/Q up-conversion mixer, an I/Q local (LO) oscillator\ngenerator, and a power amplifier. To improve the linearity of the I/Q up-conversion mixer, an inverter\ntransconductor with third-order intermodulation (IM3) distortion cancellation is proposed.........................................
