A device includes a switching unit including N input ports and M output ports, wherein N&#x2265;M&#x2265;2. The switching unit is configured to selectively interconnect each of the M output ports with a different one of the N input ports. The device further includes M attenuators, wherein each of the M attenuators is electrically coupled to a different one of the M output ports of the switching unit.

Device including a switching unit and applications thereof

The present invention relates to various embodiments of a Radio-Frequency (RF) front-end for use in a receiver, a diversity receiver and a method for operating a diversity receiver.

Radio-frequency front-end and receiver

A device or system for transmission and reception for voice or data communication applications. The device or system is capable of duplex operation and adapted to operate in an environment using a plurality of frequency bands. The present disclosure also relates to a communication means including a transmitter and receiver arrangement and to antennas.

Multiband RF device

An integrated circuit has a clock subsystem, and a circuit. The clock subsystem is configured to provide a reference clock signal to a first module and a second module. The circuit is configured to distribute information describing characteristics of the reference clock signal to the second module. The information distributed with the circuit enables the second module to adapt the reference clock signal based on the information.

Systems and method for implementing a transmitter with hybrid closed loop power control in a communication device.

Transmitter with hybrid closed loop power control

A filter stage for use in a receiver includes a switch with an input coupled to an antenna terminal, a first output and a second output; a first filter of a first type coupled to the first output; and a second filter of a second type different from the first type, coupled to the second output. A receiver includes a filter stage as mentioned above; and a switching unit coupled to the filter stage for controlling a switching state of the switch, to selectively connect the antenna terminal to the second output, depending on a selection signal.

High-frequency prestage and receiver

A circuit includes a phase shifter configured to selectively shift a phase of a baseband phase signal in accordance with a zero crossing signal to output a selectively phase-shifted signal, a phase modulator configured to provide a phase modulated carrier signal in accordance with the selectively phase-shifted signal, and an inverter configured to selectively invert the phase modulated carrier signal in accordance with the zero crossing signal.

Jumpless phase modulation in a polar modulation environment

An automatic fuse architecture is described. An incoming signal is received and detected to determine whether the signal exceeds a threshold value.

Automatic fuse architecture

The present disclosure relates to circuits and methods for improving the performance of a polar modulator by maintaining the input to a phase modulator.

Phase locked loops systems and control apparatus therefor are presented, in which a first charge pump bias current is generated according to a sensed VCO tuning voltage and a second generally constant bias current is provided. The provision of the first and second bias currents allows compensation for non-linear VCO tuning sensitivity. Methods are also presented for biasing a charge pump, including selectively providing a first current to the charge pump using a first current source, controlling the first current according to a VCO tuning voltage of the phase locked loop system, and providing a substantially constant second current to the charge pump.
