    Abstract: A method and apparatus for frequency conversion. The apparatus includes a mixer configured to provide an output signal with a converted frequency, a local oscillator, and a non-linear transmission structure operably connected to the mixer and the local oscillator. The non-linear transmission structure is configured to cancel at least a portion of non-linearity of the mixer from the output signal and to modify a gain of the output signal. The local oscillator may provide a local oscillator signal to the non-linear transmission structure. The non-linear transmission structure may also be configured to modify the local oscillator signal to cancel at least the portion of the non-linearity of the mixer and to modify the gain of the output signal, and provide the modified local oscillator signal to the mixer.

    Abstract: A wearable wireless communication device comprises a transceiver positioned on a first side of the device, the transceiver comprising a first antenna configured to receive radio frequency (RF) signals transmitted toward the first side of the device. The device is wearable about an object that attenuates reception, by the first antenna, of RF signals transmitted toward a second side of the device. The device further comprises a waveguide electromagnetically coupled to the transceiver, the waveguide terminating in at least a second antenna positioned on the second side of the device. The second antenna is configured to receive the RF signals transmitted toward the second side of the device. The waveguide is shaped to direct received RF signals around the object to the transceiver. The object may in some embodiments be a piece of human anatomy.

    Abstract: A master voltage controlled oscillator (VCO) produces an output signal at an operating frequency of at least 100 gigaHertz (GHz). A buffer VCO injection-locked to an output of the master VCO produces an output signal at the operating frequency with a voltage swing greater than 50% of an output voltage swing of the master VCO output signal. The buffer VCO operates without pulling, and can drive a load of at least three times greater than a nominal load. Phase noise in the output of the buffer VCO is as much as −96 decibels (dB) relative to the carrier (dBc) per Hertz (Hz) at 125 GHz with a 1 megaHertz (MHz) offset.

    Abstract: A method implemented by a device to measure a bodily parameter includes transmitting, by a transmit (Tx) antenna of an antenna pair, a first radar pulse to a receive (Rx) antenna of the antenna pair. The method also includes receiving, by the receive (Rx) antenna, the first radar pulse. The first radar pulse travels through a radar target between the Tx antenna and the Rx antenna. The method further includes transmitting, by the Tx antenna, a second radar pulse to the Rx antenna. In addition the method includes receiving, by the Rx antenna, the second radar pulse, wherein the second radar pulse travels through the radar target between the Tx antenna and the Rx antenna. The method also includes determining a bodily parameter within the radar target as a function of the transmission and the reception of the first radar pulse and the second radar pulse.
