Abstract: A system for transmitting or receiving signals may include an integrated circuit (IC), a transducer operatively coupled to the IC for converting between electrical signals and electromagnetic signals; and insulating material that fixes the locations of the transducer and IC in spaced relationship relative to each other. The system may further include a lead frame providing external connections to conductors on the IC. An electromagnetic-energy directing assembly may be mounted relative to the transducer for directing electromagnetic energy in a region including the transducer and in a direction away from the IC. The directing assembly may include the lead frame, a printed circuit board ground plane, or external conductive elements spaced from the transducer. In a receiver, a signal-detector circuit may be responsive to a monitor signal representative of a received first radio-frequency electrical signal for generating a control signal that enables or disables an output from the receiver.

Abstract: A test fixture has a flexible plastic cable that acts as a waveguide. The Device-Under-Test (DUT) is a small transceiver and antenna that operate in the Extremely High-Frequency (EHF) band of 30-300 GHz. The size of the DUT transceiver is very small, limiting the power of emitted electromagnetic radiation so that close-proximity communication is used. The envelope for reception may only extend for about a centimeter from the DUT transceiver, about the same size as the test socket. A slot is formed in the test socket very near to the antenna. The slot receives one end of the plastic waveguide. The slot extends into the envelope by the DUT transceiver so that close-proximity radiation is captured by the plastic waveguide. The waveguide has a high relative permittivity and reflective metalized walls so that the radiation may be carried to a receiver that is outside the envelope.

Abstract: A communication device employs a contactless secure communication interface to transmit and receive data with a computing device using close proximity extremely high frequency (EHF) communication. The communication device and the computing device periodically initiate a discovery operation mode, whereby the devices periodically transmit identifying information about the respective devices and listen for identifying information from the other device. Upon completion of the discovery mode operation, the devices enter a link-training operation mode and exchange capability information about the respective devices. During transport mode operation the communication device employs methods to manage access to data stored on the communication device by encrypting the data using one or a combination of training information or capability information as a basis for generating an encryption key.

Abstract: An electromagnetic Extremely High Frequency (EHF) communication chip includes one or more local oscillator circuits, a transducer circuit and at least one of a modulator or a demodulator coupled to the transducer circuit. Each of the local oscillator circuits may have a local oscillator and configured collectively to generate first and second carrier signals having respective first and second EHF frequencies. The first EHF frequency may be different than the second EHF frequency. The transducer circuit may have a first transducer for transmitting and receiving EHF communication signals. The modulator may be coupled to the local oscillator circuits for modulating the first carrier signal or the second carrier signal with a first transmit base data signal. The demodulator may be for demodulating the first carrier signal or the second carrier signal to produce a first receive base data signal.

Abstract: A system for sensing proximity using EHF signals may include a communication circuit configured to transmit via a transducer an EM signal at an EHF frequency, and a proximity sensing circuit configured to sense a nearby transducer field-modifying object by detecting characteristics of a signal within the communication circuit. A system for determining distance using EHF signals may include a detecting circuit coupled to a transmitting communication circuit and a receiving communication circuit, both communication circuits being mounted on a first surface. The transmitting communication circuit may transmit a signal toward a second surface, and the receiving communication circuit may receive a signal relayed from the second surface. The detecting circuit may determine distance between the first surface and a second surface based on propagation characteristics of the signals.

Abstract: Docked devices communicate wirelessly and in close proximity using multiple transmitters of Extremely High-Frequency (EHF) signals of 30-300 GHz. The devices may not be precisely aligned when docked. Tolerance of misalignment is improved by adding barriers such as solid metal blocks or rows of metal-filled vias that have a spacing of less than one-quarter the EHF wavelength. The barriers reflect EHF radiation and prevent EHF radiation from penetrating the barrier. Barriers placed between adjacent transmitters and receivers block stray electromagnetic radiation from causing cross-talk. The barriers can be placed closer to the transmitters than to the receivers to allow for a wider area for reception, permitting a wider misalignment. EHF reflecting features such as ground planes spaced a quarter-wavelength apart may be added to an end of a substrate near a connecting edge to act as a barrier and reflect electromagnetic radiation back toward an intended receiver.
