Abstract: 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.

Abstract: 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.

Abstract: A radar system with frequency conversion includes a signal generator configured to generate an input signal at a first frequency. A transmitting interposer is configured to receive the input signal from the signal generator. The transmitting interposer includes a transmitting front-end module configured to upconvert the input signal at the first frequency to an outgoing radar signal at a second frequency greater than the first frequency, and a transmitting antenna module having a plurality of transmitting patches configured to radiate the outgoing radar signal. A receiving interposer is configured to transmit an output signal to the signal generator. The receiving interposer includes a receiving antenna module having a plurality of receiving patches configured to capture an incoming radar signal at the second frequency, and a receiving front-end module configured to downconvert the incoming radar signal at the second frequency to the output signal at the first frequency.
