A method and apparatus correcting errors associated with timing offsets in radiofrequency coils. The method and apparatus include a memory element and a controller. The controller is configured to execute a set of instructions to receive data of a plurality of signals, the plurality of signals comprising at least one projection echo. The controller is also configured to identify a plurality of offsets of the plurality of signals based on the at least one projection echo. The controller is also configured to apply the plurality of offsets to a k-space of the plurality of signals.

Method for correcting errors associated with asynchronous timing offsets between transmit and receive clocks in MRI wireless radiofrequency coils

An apparatus and method amplify a signal for use in a wireless network. The apparatus includes a power amplifier, an envelope modulator, a tunable matching network (TMN), and a controller. The power amplifier outputs the signal at an output power. The envelope modulator controls a bias setting for the power amplifier. The TMN includes a plurality of immittance elements. The controller is operably connected the envelope modulator and the TMN. The controller identifies a desired value for the output power of the power amplifier, controls the output power of the power amplifier by modifying the bias setting of the power amplifier, and sets a number of the plurality of immittance elements based on the bias setting of the power amplifier.

Apparatus and method for a tunable multi-mode multi-band power amplifier module

An apparatus and method manage impedance values in a radio in a wireless network. The apparatus includes a tunable matching network (TMN) positioned on a path between a transceiver and an antenna. The TMN includes a plurality of immittance elements. A voltage standing wave ratio (VSWR) detector is configured to detect a ratio of a signal passing the VSWR detector and a signal reflected from the TMN. A control circuit is configured to identify an operating setting for the radio, set a number of the immittance elements based on the operating setting, monitor the ratio detected by the VSWR detector, and modify a setting of at least one of the immittance elements based on the ratio detected.

An apparatus and method for amplifying a transmission signals in multiple modes and multiple bands. The apparatus includes a tunable power amplifying module adapted to receive a plurality of signal types comprising multiple modes and multiple bands. The tunable power amplifying module includes a first and second power amplifier stages and a number of tunable matching networks configured to optimize an impedance value based on the mode and band of the signal to be amplified.

The present disclosure relates generally to digitally tunable impedance matching networks. In one example, a digitally tunable impedance matching network is configured to produce an overall reactance value of approximately X, and includes multiple reactive components that are configured to produce a reactance value in the range of approximately zero to X with a minimum resolution of approximately X/2.

System and method for a digitally tunable impedance matching network

A lockable MEMS switching architecture provided having a clutch assembly, a switching member, and an actuator. The clutch assembly has one or more engagement features located in proximity to the switching member&#x2014;particularly one or more receiving features located upon the switching member. The clutch assembly is actuated to disengage the engagement features from the receiving features. The switching member is actuated to move in relation to the clutch assembly. Once the switching member is in a desired position, the clutch assembly is de-actuated, causing the engagement features to re-engage with the switching member, thereby restricting its further movement.

The present disclosure relates generally to tunable impedance matching networks and methods for the use of such networks. In one example, a method includes identifying state information about a mobile device, accessing a memory to identify a configuration of an impedance matching network based on the state information, and applying the values from the configuration to the impedance matching network.
