Patent number: 10469123Abstract: A radio frequency front end module is provided for a high power capability and a high signal band selectivity. The front end module includes an external filter and an integrated circuit coupled with the external filter via two external filter leads. The integrated circuit includes a transmit-receive switch, a power amplifier and a low noise amplifier. The transmit-receive switch alternates between coupling an antenna port to a transmit port and coupling the antenna port to a receive port. The power amplifier amplifies a modulated radio frequency signal. The low noise amplifier amplifies a received radio frequency signal when the antenna port is coupled to the receive port. The external filter can be replaced to adapt to various requirements of signal frequency bands, without the need of modifying the layout of the integrated circuit.Type: GrantFiled: October 30, 2017Date of Patent: November 5, 2019Assignee: NETGEAR, INC.Inventor: Joseph Amalan Arul Emmanuel

Patent number: 10412687Abstract: Various of the disclosed embodiments improve the operations of a combined access point/Cable modem. Though the access point component and the Cable modem component may perform operations in different spectrums, harmonics in the Cable spectrum may interfere with operations, e.g., in the 2.4 GHz and 5 GHz range, of the access point. Some embodiments implement a remediation and/or channel transition process for the access point following detection of Cable-related interference. During remediation, the device may, e.g., adjust the wireless power levels, EDCA backoff times, signal thresholds, etc. In some embodiments, if the remediation actions prove ineffective, the wireless peers may be relocated to a channel further from the interfering Cable harmonics. The determination to remediate or reallocate may be based on various contextual factors, e.g., the character of the peer devices and the applications being run.Type: GrantFiled: July 17, 2017Date of Patent: September 10, 2019Assignee: NETGEAR, INC.Inventors: Joseph Amalan Arul Emmanuel, Peiman Amini, Shahrokh Mehroziad Zardoshti

Patent number: 10410948Abstract: A heat sink and an EMI shield are integrated via injection molding. The heat sink and the EMI shield may be molded together as an integrated unit with an intervening non-electrically conductive layer formed between the heat sink and the EMI shield during the injection molding process. The integrated molded unit could also be molded to a thermally conductive layer comprising another material such as an elastomer suitable for more precisely conforming to the contours of an electrical component for maximizing thermal transfer. Accordingly, the number of steps and amount of materials required to provide thermal dissipation and EMI protection for an electrical component may be reduced.Type: GrantFiled: January 30, 2015Date of Patent: September 10, 2019Assignee: Netgear, Inc.Inventors: John Ramones, Arun Raghupathy

Patent number: 10342017Abstract: Wireless communication under IEEE 802.11 standards utilizing carrier specific interference mitigation where an AP or UE employs an ultra-wideband tuner to evaluate available spectrum between several communication bands. Rather than being constrained to communicate in a single communication band, the AP and UEs may utilize more than one communication band to communicate with one another. In doing so, the AP and UE search across several bands and measure interference on a carrier-by-carrier basis across those bands. Either of the AP and UE may select a cluster of carriers for communication, where the cluster of carriers may comprise 1) contiguous carriers in a single sub-channel, 2) contiguous carriers spanning across more than one sub-channel, 3) discontinuous carriers in a single sub-channel, or 4) discontinuous carriers spanning across more than one sub-channel. The mapping between a cluster and its carriers can be fixed or reconfigurable.Type: GrantFiled: June 27, 2018Date of Patent: July 2, 2019Assignee: NETGEAR, Inc.Inventor: Michael Clegg

Electronic device with antenna integrated connector shroud for wireless communication of diagnostics
Patent number: 10297898Abstract: The subject matter disclosed herein describes integrating an antenna with a connector shroud of an electronic device used for conducting diagnostics. By integrating the antenna with the connector shroud, the device can be made smaller while still allowing for effective communication of results wirelessly to a remote system. In implementations such as On-board Diagnostics (OBD) II for motor vehicles, this may allow the device to remain present in the vehicle, conveniently while driving, for continuous monitoring and diagnostic feedback to a remote system, by consuming the least amount of space which may be needed by the driver.Type: GrantFiled: December 9, 2016Date of Patent: May 21, 2019Assignee: Netgear, Inc.Inventor: Todd Van Cleave -
