Abstract: A contactless, electromagnetic (EM) replacement for cabled Standards-based interfaces (such as USB, I2S) which handles data transfer requirements associated with the Standard, and capable of measuring and replicating relevant physical conditions on data lines so as to function compatibly and transparently with the Standard. A contactless link between devices having transceivers. A non-conducting housing enclosing the devices. A dielectric coupler facilitating communication between communications chips. Conductive paths or an inductive link providing power between devices. An audio adapter communicates over a contactless link with a source device, and via a physical link with a destination device such as a conventional headset. Power may be provided to the adapter from the source device, and by the adapter to the destination device.

Abstract: An EHF receiver that determines an initial slicing voltage level and dynamically adjusts the slicing voltage level and/or amplifier gain levels to account for characteristics of the received EHF electromagnetic data signal. The architecture includes an amplifier, detector, adaptive signal slicer, and controller. The detector includes a main detector and replica detector that convert the received EHF electromagnetic data signal into a baseband signal and a reference signal. The controller uses the baseband signal and reference signal to determine an initial slicing voltage level, and dynamically adjust the slicing voltage level and the gain settings of the amplifier to compensate for changing signal conditions.

Abstract: Embodiments discussed herein refer to systems, methods, and circuits for establishing EHF contactless communications links. The EHF contactless communication link may serve as an alternative to conventional board-to-board and device-to-device connectors. The link may be a low-latency protocol-transparent communication link capable of supporting a range of data rates. The link may be established through a close proximity coupling between devices, each including at least one EHF communication unit. Each EHF unit involved in establishing an EHF communication link may progress through a series of steps before data can be transferred between the devices. These steps may be controlled by one or more state machines that are being implemented in each EHF communication unit.

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 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 Physical Layer (PHY) of a host system of an electronic device may be implemented as a contactless PHY (cPHY) for extremely high frequency (EHF) contactless communication and the operation of EHF transmitters (TX), receivers (RX) and transceivers (EHF-XCVR) in an extremely high frequency integrated circuit (EHF IC) of the electronic device. The Host-cPHY translates logical communications requests from the Link Layer (LINK) into hardware-specific operations to affect transmission or reception of signals over an EHF contactless link. The Link Layer (LINK) may also be optimized as a contactless Link Layer (cLINK) for EHF contactless communication. A virtualized contactless Physical Layer (VcPHY) may comprise a contactless Physical Layer (Host-cPHY), and a contactless Link Layer (cLINK) for coupling a conventional Link Layer (LINK) with the contactless Physical Layer (Host-cPHY). Multiple data streams may be transported over the EHF contactless link over a range of frequencies.

Abstract: Establishing a communication link may include transmitting by a first device an unmodulated first electromagnetic EHF signal and receiving by a second device the first electromagnetic EHF signal. The second device may determine whether the received first electromagnetic EHF signal indicates that a first shield portion and a second shield portion are in alignment. The transmission of a modulated second electromagnetic EHF signal may be enabled when the received first electromagnetic EHF signal indicates that both the shield portions are in alignment and may be disabled when the received first electromagnetic EHF signal indicates that the first and second shield portions are not in alignment.
