The present application relates to a method and apparatus for implementing a radar array including a gate bias source for providing a first variable voltage, a back gate well control for providing a second variable voltage, and a field effect transistor having a drain, a source, a gate and a back gate well control, the field effect transistor being further configured to couple an alternating current radar signal between the drain and the source and to adjust a phase of the alternating current radar in response to first variable voltage applied to the gate and the second variable voltage applied to the back gate well control.

Field effect transistor (FET) configured to phase shift a radar signal using first and second variable voltages applied to a gate and a back gate of the FET

A radar system includes a transmit section to emit a transmit signal. A chip-based front-end portion of the transmit section increases a frequency of an input signal to produce an intermediate signal and amplifies signal strength of the intermediate signal to produce the transmit signal. The frequency of the input signal is in a range of 76 gigahertz (GHz) to 80 GHz. The radar system also includes a receive section to receive a reflected signal resulting from reflection of the transmit signal by an object.

Chip-based transmit channel architecture

A receiver apparatus is provided. The apparatus includes a single field effect transistor mixer comprising a gate, a source and a drain, wherein one of the source or the drain is configured to receive a first signal from a first low noise amplifier at a receiving frequency and another of the source or the drain is configured to output a second signal at an intermediate frequency to a second low noise amplifier; and a local oscillator configured to apply a third signal to the gate.
