  • Patent number: 11221395
    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.

  • Patent number: 10797647
    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.

  • Publication number: 20050048747
    Abstract: A method for fabricating a semiconductor device which protects the ohmic metal contacts and the channel of the device during subsequent high temperature processing steps is explained. An encapsulation layer is used to cover the channel and ohmic metal contacts. The present invention provides a substrate on which a plurality of semiconductor layers are deposited. The semiconductor layers act as the channel of the device. The semiconductor layers are covered with an encapsulation layer. A portion of the encapsulation layer and the plurality of semiconductor layers are removed, wherein ohmic metal contacts are deposited. The ohmic metal contacts are then annealed to help reduce their resistance. The encapsulation layer ensures that the ohmic metal contacts do not migrate during the annealing step and that the channel is not harmed by the high temperatures needed during the annealing step.
