Patent number: 10615828Abstract: A flexible multi-channel diversity wireless audio receiver system for routing, processing, and combining multiple radio frequency (RF) signals containing audio signals received on respective antennas is provided. The wireless audio receiver system provides flexible routing of multiple RF signals in different selectable modes, and low latency uninterrupted reception of signals in harsh RF environments by combining multiple RF signals to maximize signal-to-noise ratio. The audio output may be generated in an uninterrupted fashion and mitigate multipath fading, interference, and asymmetrical noise issues. Received RF signals may also be cascaded by the wireless audio receiver system to allow daisy chaining.Type: GrantFiled: February 28, 2019Date of Patent: April 7, 2020Assignee: Shure Acquisition Holdings, Inc.Inventors: Thomas J. Kundmann, Michael Goodson, Robert Mamola, Jeffrey Arthur Meunier, Robert Szopko, Yang Tang

Patent number: 9667216Abstract: A wideband tunable combiner system for a dual frequency diversity transmitter is provided that includes a tunable capacitance network. Incoherent RF signals with the same audio signal may be combined with the system into a combined RF signal for transmission on an antenna. The tunable capacitance network, in conjunction with a combiner and a band pass filter, may optimize the isolation between the incoherent RF signals and reduce intermodulation, while maintaining a wide operating bandwidth. The capacitance value of the tunable capacitance network may be selected based on the frequencies of the incoherent RF signals, RF spectrum information, or antenna loading data. An RF transmitter including the tunable combiner system may have improved spectral efficiency and performance and take advantage of available spectrum.Type: GrantFiled: August 12, 2015Date of Patent: May 30, 2017Assignee: Shure Acquisition Holdings, Inc.Inventor: Robert Szopko

Patent number: 7092684Abstract: An interference canceller 200 and corresponding method thereof operates to reduce the level of an interfering signal and includes a circulator 202 comprising a transmitter port, a receiver port and an antenna port, a transmission line 210 comprising a first end coupled to the transmitter port and a second end for coupling to a signal source; and a circuit 216, having an input coupled to the receiver port 206 and an output coupled 220 to the transmission line, for providing a phase shifted version of a signal coupled to the input at the output, wherein an interfering signal at the antenna port is reverse coupled to the transmission line by the circulator and coupled to the input of the circuit so as to reduce an amplitude of the interfering signal at the second end 212 of the transmission line. The interference canceller concepts may advantageously be used in a single transmitter version or in a multiple transmitter version (FIG. 4).Type: GrantFiled: March 31, 2003Date of Patent: August 15, 2006Assignee: Motorola, Inc.Inventors: Robert Szopko, Justin N.
