Patent number: 11412395Abstract: Certain aspects are directed to an intermodulation detection sub-system. The intermodulation detection sub-system includes a test signal generation module, at least one intermodulation detection device, and a controller. The test signal generation module is integrated into a unit of a telecommunications system. The test signal generation module is configured to provide a test signal to a remote antenna unit of the telecommunications system. The intermodulation detection device is integrated into the telecommunications system. The intermodulation detection device is configured to detect intermodulation products generated by mixing a first signal component and a second signal component of the test signal. The controller is integrated into the unit. The controller is configured to control the test signal generation module and the at least one intermodulation detection device.Type: GrantFiled: April 1, 2015Date of Patent: August 9, 2022Assignee: Andrew Wireless Systems GmbHInventors: Gregory Allan Maca, Udo-Michael Vetter

Patent number: 9948262Abstract: In one embodiment, a signal-processing apparatus for generating an amplified output signal based on an input signal is provided. The apparatus comprises: an amplifier configured to generate the output signal, wherein the amplifier is configured to receive a supply voltage; and a limiter configured to inhibit increases in the input signal power level from being applied to the amplifier, wherein the limiter comprises: a variable attenuator configured to selectively attenuate the input signal before being applied to the amplifier; wherein the limiter integrates over a voltage difference between a current measure of attenuated input signal power level and a limiter threshold level to control a level of attenuation applied by the variable attenuator to the input signal.Type: GrantFiled: April 7, 2017Date of Patent: April 17, 2018Assignee: Andrew Wireless Systems GmbHInventor: Udo-Michael Vetter

Patent number: 9641131Abstract: A signal-processing system has an amplifier that generates an amplified (RF) output signal based on an (RF) input signal. The amplifier receives a supply voltage that can be selectively set to an appropriate level between a lower power supply level and a higher power supply level. With one power supply permanently connected to the supply voltage node, a control unit executes software to toggle a supply switch to periodically connect and disconnect the other power supply thereby generating a weighted average value for the supply voltage between the two power supply levels. When a sudden and large increase occurs in the (input) power level, hardware-interrupt circuitry interrupts and supersedes the software-based control of the supply-voltage switch to quickly switch the supply voltage towards the higher power supply level. The hardware-interrupt circuitry handles such situations faster than the software-based control in order to prevent a limit violation of spectrum emission requirements.Type: GrantFiled: November 22, 2011Date of Patent: May 2, 2017Assignee: Andrew Wireless Systems GmbHInventor: Udo-Michael Vetter
