Abstract: An amplifier module comprises an amplifier with an output and a coupling element for receiving a signal at the output. It also comprises a control input for receiving a control signal and a power detector which can be changed over and is intended to determine a power signal from the signal. The power detector which can be changed over is coupled to the control input and is set up in such a manner that a dynamic range of the power detector can be changed on the basis of the control signal.
Abstract: A transmitting and receiving arrangement as well as a method for transmission of monitoring and/or payload data in a transmitting and receiving arrangement for a wirefree communications system has a device which processes baseband for processing digital signals to form a baseband signal and a device which processes radio frequency for conversion of the baseband signal to a radio frequency signal. Monitoring and/or payload data are/is transmitted in the form of data packets via at least one channel of a channel-oriented link between the device which processes baseband and the device which processes radio frequency.

Abstract: A transmitting arrangement includes a matching circuit, a reference circuit and a comparator. The output of the matching circuit can be coupled to an antenna and comprises an adjustable impedance. The reference circuit is connected to an input of the matching circuit and comprises a reference impedance. Inputs of the comparator are coupled to the matching circuit and the reference circuit and its output is coupled to the adjustable impedance via a control input of the matching circuit.
Abstract: A data switch (4) is proposed which can be operated such that it generates a MA table of MAC addresses of devices associated with some of its ports (9, 13, 15, 17, 19), but not the MAC addresses associated with one of the ports (11). Packets received by the switch, other than from the port (11), are assumed to be destined for the port (11) and are transmitted via the port (11). If the port (11) is connected to a network, and all the other ports are connected to a relatively small number of devices, such as one device per port, then the memory requirement to store the MA table is dramatically reduced.
Abstract: A polar modulator including a signal converter configured to provide a phase signal and an amplitude signal based on at least one received signal is disclosed. A digital-to-analog converter is coupled to the signal converter, the digital-to-analog converter configured to receive an augmented signal, wherein a polarity of the augmented signal is selected to minimize an absolute phase change for sequential signals. A signal mixer is coupled to the digital-to-analog converter to receive an analog signal generated from the augmented signal.
Abstract: This disclosure relates to low noise amplifiers (LNAs) and more particularly to LNAs integrated on integrated circuit (IC) chips along with radio frequency (RF) amplifiers.

Abstract: A multi-carrier information transceiver that exhibits robustness against radio frequency interference (RFI) signals present in the communications channel. The transceiver includes a RFI mitigation technique that operates not only during the steady state operation of the transceiver but also during the training stage of the transceiver. That requires dynamically modifying the training signals when the presence of RFI is detected. The modification of the training signals facilitates the estimation of RFI, improving the performance of the multi-carrier transceiver.

Abstract: In one implementation, a polar transmitter includes a digital signal processing component that processes baseband signals and provides a baseband data signal with amplitude values; and a digital pre-distortion component that receives the baseband data signal with amplitude values, compensates for jitter error in the baseband data signal with amplitude values, and provides an adjusted modulated signal.
