Integrated transmit and receiveMMICs for automotive applications have been realized in coplanar waveguide technology, using a 0.15 ym PHEMT process. The transmitter chip delivers an output power of 10dBm at the antenna and the LO-ports. The receiver has an overall conversion gain of 10 dB for an LO-power of -10dBm. Both chips only require an area of 3x2 mm2. For an improved higher power version of the transmitter, a new nonlinear HEMT-model has been used for the design of a power amplifier, resulting in excellent agreement between predicted and measured output performance at 76 GHz.
