Briefly, a wireless communication device having two or more different wireless radio frequency (RF) units operably coupled to a router by two or more respective buses. The router is able to route bit streams of radio frequency signals from a digital baseband unit to one of the two or more RF units via one of the two or more buses. A method for routing the bit streams is also provided.

The peak-to-average power ratio at the output of an rf power amplifier is detected and compared with, for instance, an ideal ratio. The result of this comparison is used to control the amplifier, particularly to reduce distortion in the output signal.

Embodiments of a multi-mode receiver, transmitter, and method are generally described herein. Other embodiments may be described and claimed. In some embodiments, a sliding IF architecture that uses a zero-IF mixer and partially overlapping baseband filters is employed to operate over various bandwidths and help remove adjacent interferers.

Briefly, some embodiments of the invention provide devices, systems and methods of multiple transceivers control. For example, a method in accordance with an embodiment of the invention may include determining whether interference is expected between an intended activity of a first wireless transceiver of a wireless communication station and an activity of a second wireless transceiver of said wireless communication station; and based on the determination result, modifying an operational parameter of an interference reducer of said wireless communication station.

In one exemplary embodiment of the invention, an outphasing modulator may include at least a multiplier to multiply an amplitude modulation signal by a phase modulated carrier signal to generate a modulated signal. The outphasing modulator may also include a phase splitter to phase split the modulated signal to generate phase shifted modulated signals. The outphasing modulator may also include a sum-difference combiner to produce outphased modulated signals from the phase shifted modulated signals.

Outphasing modulators and methods of outphasing modulation

In some embodiments of the present invention, multiple voltage controlled capacitor branches may be employed in a tuning circuit. Each of the multiple voltage controlled capacitors branches may be set to somewhat apart resonance frequency so that a composite resonance derivative curve forms an equi-ripple curve with an improved tuning sensitivity linearization.

Device, system and method to provide different bias voltages and common tuning voltage

An apparatus in accordance with one embodiment of the present invention may include a local oscillator having an electroacoustic resonator; and zero intermediate frequency signal processing circuitry coupled to the local oscillator. In certain embodiments, the electroacoustic oscillator may be a thin film bulk acoustic resonator.

Using an electroacoustic resonator

Embodiments of the invention describe a modulator having first and second synthesizers, for example, fractional-N synthesizers, that generate first and second outphased modulated signals with aligned phases. Embodiments of the modulator may align the phases of the outphased signals using first and second feedback loops associated with first and second modulation paths of the modulator.

Automatic gain control (AGC) functionality is distributed within a transmitter chain. A controller manages two or more variable gain amplifiers to achieve the desired result.

Distributed transmitter automatic gain control

A transmitter synthesizes a signal having a phase modulated component and an amplitude modulated component. Phase and amplitude reference signals are generated from phase and amplitude information extracted from an offset output and offset input signal. An origin-offset signal source generates a compensation signal which is combined with the input and output signals to generate the offset input and output signals.

Method and polar-loop transmitter with origin offset for zero-crossing signals

In a switching scheme mechanical MEMs switches are connected in parallel with solid state switches. This parallel MEMS/solid-state switch arrangement takes advantage of the fast switching speeds of the solid state switches as well advantage of the improved insertion loss and isolation characteristics of the MEMS switches. The solid-state switches only need to be energized during a ramp up/down period associated with the slower MEMs switch thus conserving power. As an additional advantage, using a solid-state switch in parallel with MEMs switches improves the transient spectrum of the system during switching operations.
