Patent number: 10404503Abstract: Aspects of methods and systems for frequency multiplexing suitable for Data Over Cable Service Interface Specification (DOCSIS) are provided. A system for multiplexing signals according to frequency comprises a DOCSIS port interface, an upstream interface, a downstream interface, and a circulator subsystem. The DOCSIS port interface comprises a plurality of channel filters. The upstream interface is operably coupled to a first channel filter of the plurality of channel filters, and the downstream interface is operably coupled to a second channel filter of the plurality of channel filters. The circulator subsystem is able to direct a first signal from the upstream interface to the DOCSIS port interface and is able to direct a second signal from the DOCSIS port interface to the downstream interface.Type: GrantFiled: June 13, 2017Date of Patent: September 3, 2019Assignee: Maxlinear, Inc.Inventors: Paul Chominski, Sridhar Ramesh

Patent number: 10347414Abstract: Methods and systems for winding transformers to maximize symmetry of the primary and secondary coils may comprise a transformer with a primary coil and a secondary coil. A first portion of the transformer has at least one turn around a core, and includes twisted pair sections of the primary coil and secondary coil. A second portion of the transformer may include a fractional turn extension of only the primary coil at one end of the first portion, and a third portion of the transformer may include a fractional turn extension of only the secondary coil at an opposite end of the first portion, where the fractional turn extensions area equal in length. A center tap may be coupled to the first portion of the transformer, which may be a balun. The transformer may comprise an off-chip transformer that includes wires wound around a magnetic core.Type: GrantFiled: May 13, 2016Date of Patent: July 9, 2019Assignee: Maxlinear, Inc.Inventor: Paul Chominski

Patent number: 9258621Abstract: A multi-service antenna may comprise: a support structure, a reflector mounted to the support structure, a signal processing assembly mounted with the support structure, a first wire strung between the reflector and the support structure and/or the signal processing assembly, and circuitry for processing a first signal received as a result of electromagnetic radiation (e.g., terrestrial television and/or cellular signals) incident on the first wire. The circuitry for processing the first signal may be housed in the signal processing assembly. A second wire may also be strung between the reflector and the support structure and/or the signal processing assembly, and the circuitry may be operable to perform diversity processing of signals received via the two wires.Type: GrantFiled: July 28, 2014Date of Patent: February 9, 2016Assignee: Maxlinear, Inc.Inventors: Curtis Ling, Paul Chominski

Patent number: 8515375Abstract: A receiver includes a mixer, a filter, a received signal strength indicator, and a control loop. The mixer is adapted to convert the frequency of a received signal. The filter is adapted to filter out undesired signals that may be present in the output signal of the mixer. The received signal strength indicator is adapted to detect blocker (also known as jammer) signals that may be present in the output signal of the low-pass filter and generate a feedback signal in response. The control loop is adapted to vary its bandwidth in response to the feedback signal of the received signal strength indicator. The control loop supplies an oscillating signal to the mixer.Type: GrantFiled: November 11, 2010Date of Patent: August 20, 2013Assignee: Maxlinear, Inc.Inventors: Sheng Ye, Paul Chominski

Patent number: 7417515Abstract: An on-chip antenna switching scheme for Gigahertz frequencies where for the transmission path a first on-chip switching means is coupled between an on-chip power amplifier and an antenna. In the receiving path a second on-chip switching means at an input to an on-chip low noise amplifier (LNA) connects to ground. Coupled off-chip between the first switching means and antenna and antenna and the second switching means are impedance matching means and a half and a quarter wavelength line, respectively. In transmission mode both switching means are closed, in receiving mode both switching means are open. This allows for optimal transmission of the signal in either direction.Type: GrantFiled: May 15, 2006Date of Patent: August 26, 2008Assignee: Jaalaa, Inc.Inventor: Paul Chominski
