Patent number: 7580684Abstract: A fully integrated, programmable mixed-signal radio transceiver comprising a radio frequency integrated circuit (RFIC) which is frequency and protocol agnostic with digital inputs and outputs, the radio transceiver being programmable and configurable for multiple radio frequency bands and standards and being capable of connecting to many networks and service providers. The RFIC includes a tunable resonant circuit that includes a transmission line having an inductance, a plurality of switchable capacitors configured to be switched into and out of the tunable resonant circuit in response to a first control signal, and at least one variable capacitor that can be varied in response to a second control signal, wherein a center resonant frequency of the resonant circuit is electronically tunable responsive to the first and second control signals that control a first capacitance value of the plurality of switchable capacitors and a second capacitance value of the at least one variable capacitor.Type: GrantFiled: February 10, 2005Date of Patent: August 25, 2009Assignee: BitWave Semiconductor, Inc.Inventors: Russell J.

Patent number: 7508898Abstract: A fully integrated, programmable mixed-signal transceiver comprising a radio frequency integrated circuit (RFIC) which is frequency and protocol agnostic with digital inputs and outputs, the transceiver being programmable and configurable for multiple radio frequency bands and standards and being capable of connecting to many networks and service providers. The RFIC does not use spiral inductors and instead includes transmission line inductors allowing for improved scalability. Components of the transceiver are programmable to allow the transceiver to switch between different frequency bands of operating. Frequency switching can be accomplished though the content of digital registers coupled to the components.Type: GrantFiled: August 11, 2005Date of Patent: March 24, 2009Assignee: BitWave Semiconductor, Inc.Inventors: Russell J.

Patent number: 5697078Abstract: Channel use in a wireless communication system is monitored for each radio frequency channel spanning a broad allocated bandwidth simultaneously. A transmission having signals in channels spanning the bandwidth is broadband downconverted in analog before being transformed to produce an instantaneous representation of signal levels in each channel. The instantaneous representation is stored. In addition, a statistic characterizing historical use of at least one of the channels in the bandwidth is calculated from the instantaneous representation.Type: GrantFiled: March 1, 1996Date of Patent: December 9, 1997Assignee: Steinbrecher CorporationInventors: Dean F. Peterson, Russell J. Cyr, Derek W. Gallon, James C. Camp

Patent number: 5061944Abstract: This Yagi-Uda-type antenna includes also a sleeve embracing the dipole. The sleeve may be a closed cylindrical element surrounding the dipole or it may comprise a pair of discrete elements forming an "open sleeve". The dipole, sleeve, reflector, and director elements may be in filamentary form, or they may be fabricated from stripline.Type: GrantFiled: September 1, 1989Date of Patent: October 29, 1991Assignee: Lockheed Sanders, Inc.Inventors: Richard L. Powers, Russell J. Cyr
