  • Patent number: 10181823
    Abstract: A ultra-compact coupler designed to sample the actual output power of a power amplifier and which is “VSWR insensitive”, such that reflected power is essentially not coupled to a detector circuit and only forward power is detected and processed. In a first embodiment, a coupler is situated between the final amplifier stage of a power amplifier and an output impedance matching network, and is specially configured for operation in a low impedance environment in conjunction with a detector circuit, thereby substantially reducing the areal size of the coupler. In a second embodiment, a coupler is integrated within an output impedance matching network coupled to the final amplifier stage of a power amplifier so as to share an inductor between the coupler and the output impedance matching network, thereby further substantially reducing the areal size of the coupler.

Embodiments of the invention include one or more on-chip switchable internal calibration paths that enable direct coupling of a portion of the on-chip circuit to an RF test system while isolating other circuitry on the chip. Some embodiments allow interconnection of switchable internal calibration paths between separate IC chips. Still other embodiments utilize internal switches and antenna mutual coupling to provide over-the-air calibration, alone or in combination with direct signal coupling via internal calibration paths. Periodic self-calibration of an RF IC can be performed after initial factory calibration, so that adjustments in desired performance parameters can be made while such an IC is embedded within a final system, and/or to take into account component degradation due to age or other factors.

    Abstract: Described are techniques for distributing audio data to multiple devices for a synchronized output in a manner that reduces congestion and interference with a first frequency band of a network. A first audio device receives audio data using the first frequency band, via an access point, then transmits the data to a second audio device using a different protocol. The second audio device may then distribute the audio data to other devices using a different frequency band. The two devices selected for use distributing the audio data may be determined based on signal quality for communications between the devices, data throughput between the first audio device and the access point, counts of devices that may receive data from the second device, and signal quality and other metric data associated with communications by the second audio device.

  • Patent number: 10015658
    Abstract: A portable communication system (100) maintains mission critical functionality. An accessory (120) and a handset (130) are tethered and interoperate such that the accessory operates as the primary controlling device and the handset operates as a secondary device. The accessory (120) contains a main applications processor (102) that handles non-mission critical functions. The accessory further contains a mission critical processor (104) for handling mission critical functions of transmit and receive audio as well as PTT and emergency. In response to a failure of the mission critical processor (104), the mission critical functions are maintained by handing over the mission critical functions to the non-controlling device in a manner transparent to the user. The handover is triggered in response to status changes of the mission critical processor or as a result of battery depletion. Audio paths are re-routed through backup paths (146b,148) negating reliance on processors of the accessory (120).

    Abstract: A fully integrated feedback controlled coil driver is disclosed for inductive power transfer to electronic devices. For efficient power transfer, a voltage across a switch that switchably couples the coil between a DC input power source and ground is sampled and compared with a preselected reference voltage to generate an error voltage. The error voltage is integrated over time and compared to a voltage ramp. The value of the integrated error voltage relative to the voltage ramp is used to obtain an optimal on time for the switch such that coil current is maximized for a given DC input power. The coil driver can also provide ASK modulation on the coil current by changing the size of the switch according to input data.

  • Patent number: 9385763
    Abstract: A communication device includes a receiver that is capable of canceling in -channel interference. The receiver includes an antenna for receiving a wireless signal comprising in-channel components and an out-of-channel component, wherein the in-channel components comprise a desired component and an in-channel interference component. A first filter of the receiver filters the wireless signal by blocking at least a portion of the out-of-channel component to produce a first signal comprising the in -channel components, and at least a second filter of the receiver filters the wireless signal by blocking at least a portion of the in-channel components to produce a second signal comprising the out-of-channel component. An in-channel interference estimator of the receiver generates an in-channel interference estimation signal based on the second signal. And a combiner of the filter combines the first signal and the second signal to at least partially cancel the in-channel interference component of the first signal.

  • Patent number: 9301177
    Abstract: A method and system performs antenna tuning which enhances radio frequency (RF) tuner reliability within a wireless communication device (WCD). The WCD, in response to receiving a request to change an active RF tuning state, retrieves component usage data corresponding to components of a tuning circuit that is tunable to an RF operating channel. The WCD selectively determines, using device environment state data and/or RF state data and the component usage data, an RF tuning state tuned to the RF operating channel. The selected RF tuning state (a) satisfies tuning performance specifications and (b) enhances component reliability performance by minimizing an operational wear on tuning circuit components. The WCD configures the tuning circuit using the selected RF tuning state and tracks session parameter values for tuning circuit components during a corresponding communication session.

  • Publication number: 20150147980
    Abstract: An antenna arrangement includes a switch having an open state and a closed state, a first antenna that operates as a first active driven element in a first frequency band in response to the switch being in the open state, and a second antenna that operates as a second active driven element in a first frequency band in response to the switch being in the open state. The closed state configures the first antenna and the second antenna to operate in a second frequency band different from the first frequency band by operatively coupling a first impedance between the first antenna and a radio frequency ground, and by operatively coupling a second impedance between the second antenna and the radio frequency ground. The first antenna functions as a parasitic element in the second frequency band and the second antenna functions as an active driven element in the second frequency band.
