摘要:
A communication device partition for multiple device data standards to be received on one baseband integrated circuit is described. At least two interfaces are partitioned according to the data rate speed of various types of data standards and coupled to a multimode software define radio (SDR) modem. A digital baseband processor is coupled to the multimode SDR modem and receives the various types of application data compliant with various data standards.

Structures of a system on a chip are disclosed. In one embodiment, the system on a chip (SoC) includes an RF component disposed on a first part of a substrate, a semiconductor component disposed on a second part of the substrate, the semiconductor component and the RF component sharing a common boundary, and a conductive cage disposed enclosing the RF component. The conductive cage shields the semiconductor component from electromagnetic radiation originating from the RF circuit.

A transmission arrangement for modulating useful signals onto a carrier frequency signal has a frequency generator for generating the carrier frequency signal, a first modulation path for modulating a first useful signal onto the carrier frequency signal, and a second modulation path for modulating a second useful signal onto the carrier frequency signal. The first modulation path has a digital modulator for providing an amplitude signal and a Cartesian signal pair from the first useful signal and a Cartesian modulator for modulating the Cartesian signal pair onto the carrier frequency signal in order to provide an intermediate signal. The first modulation path is configured in such a manner that the amplitude signal is modulated onto the intermediate signal in order to provide an output signal.

In one embodiment, a circuit can selectively adjust a current for driving a load. The circuit includes a sensor configured to measure a magnetic field associated with the current and provide a sensor voltage representative thereof. A control circuit is configured to selectively adjust the current as a function of the sensor voltage and a time-varying voltage threshold. Other methods and systems are also disclosed.
摘要:
A modulation device includes a signal input for receiving a data stream to be modulated and a first and a second signal output. At least one first complex component is derived from the data stream in a coding device. A first and a second high-frequency signal are output via the signal outputs. The first and second high-frequency signals are derived from the at least one first complex component and are distinguished by the fact that the second high-frequency signal has a phase shift of substantially 90° with respect to the first high-frequency signal.
