Second-order filter with notch for use in receivers to effectively suppress the transmitter blockers
Patent number: 9413326Abstract: The disclosed invention relates to a transceiver system comprising a notch filter element configured to suppress transmitter blockers (i.e., transmitter interferer signals) within a reception path. In some embodiments, the transceiver front-end comprises a differential reception path, having a first differential branch and a second differential branch, configured to provide an RF differential input signal having a transmitter blocker to a transimpedance amplifier, comprising a first-order active filter and a notch filter element. The notch filter element comprises a stop band corresponding to a frequency of a transmitted signal, such that the notch filter element suppresses the transmitted blocker without degrading the signal quality of the received differential input signal.Type: GrantFiled: July 7, 2015Date of Patent: August 9, 2016Assignee: INTEL DEUTSCHLAND GMBHInventors: Umut Basaran, Josef Schmal, Stefan Herzinger, Herbert Stockinger, Volker Thomas -

Patent number: 6486732Abstract: To keep the power consumption in the modulator-demodulator of a mobile radio as low as possible, the modulator-demodulator has a voltage-controlled oscillator. Downstream of which a divider chain having a plurality of series-connected dividers each with an even-numbered division factor is connected. Each of the dividers produces a carrier signal and a carrier signal that is orthogonal with respect thereto. A quadrature modulator for the received signal is connected to a divider of the divider chain that produces the carrier signal at the required carrier frequency. In addition, a first vector modulator is provided whose mixers are connected to the dividers of the divider chain that produce the carrier signals at the required carrier frequencies. Connected downstream of the first vector modulator is a further divider with an even-numbered division factor, and connected downstream of this is a second vector modulator for producing a transmitted signal.Type: GrantFiled: February 19, 2002Date of Patent: November 26, 2002Assignee: Infineon Technologies AGInventors: Josef Fenk, Volker Thomas, Wolfgang Thomann

Patent number: 6386057Abstract: The inventive drive device for several units of a machine has an inertia drive with an inertia drive spindle (1) driven by a motor, and several inertia drive nuts (2), the nuts being fitted on the inertia drive spindle (1) and being allocated to the units. The inertia drive nuts (2) are each arranged in the housings of the units in such a way that they can turn but cannot be displaced axially. During the rest phase of a particular unit, the inertia drive nut (2) is solidly connected to the inertia drive spindle (1) with a first positive and/or nonpositive fit. For the movement phase of the aggregate, the nut (2) is disconnected from the spindle (1) and is solidly connected to the housing with a second positive and/or nonpositive fit.Type: GrantFiled: May 8, 2000Date of Patent: May 14, 2002Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V.Inventors: Volker Thomas, Christian Harzbecker
