Publication number: 20130089130Abstract: A radio frequency receiver comprising a receiver module, an intermediate frequency (“IF”) module, a synthesizer module and a controller module. The receiver module receives a radio frequency signal and provides a baseband in-phase signal and a baseband quadrature signal, eliminates a sideband of the in-phase and quadrature signals to create a first and a second signal, downconverts the first and second signal to a first and a second IF signal, and selects one of the first or second IF signals. The IF module receives the first or second IF signal, performs analog-to-digital conversion on the first or second IF signal, and demodulates the digitally converted IF signal. The synthesizer module receives a programmable reference signal, downconverts the reference signal to an IF feedback signal, downconverts the reference signal to a baseband feedback signal, provides the IF feedback signal to the IF module, and provides the baseband feedback signal to the receiver module.Type: ApplicationFiled: September 25, 2012Publication date: April 11, 2013Inventors: Ying Shen, Guy Theberge, Richard Bourdeau, Luc Villeneuve, Fabio Concilio, Thanh Nguyen

Patent number: 8160502Abstract: The present invention provides a system for wide-range microwave communications over wireline networks. In an exemplary embodiment, a wide-range transceiver is made having pre-calibrated modular units including an IF radio processing card, an RF transmitter module, and an RF receiver module. Calibration factors are loaded into a memory (e.g., EEPROM) in each module during production. Certain additional calibration factors may also be loaded upon installation, such as a one time calibration for the type and length of cable connecting the RF unit to a remote SPU (signal processing unit). A processor in the RF unit is responsive to control signaling indicating a desired transmitter or receiver configuration (e.g., a particular frequency, bandwidth and modulation), to attenuate the signal in the transmitter/receiver path based on the predetermined calibration factors from the applicable modules. A method for calibrating the modules is also disclosed.Type: GrantFiled: April 5, 2010Date of Patent: April 17, 2012Assignee: Harris Stratex Networks, Inc.Inventors: Ying Shen, Guy Theberge, San Jao, Fabio Concilio, Shauen Thomas Trump, Don E.

Patent number: 6744314Abstract: A novel linearization apparatus for reducing power amplifier distortion does not require delay lines. The apparatus includes a power amplifier and an error generator. The signals provided by the error generator (error signal) and the power amplifier are combined to subtract out the distortion introduced by the power amplifier. The error generator includes two auxiliary amplifiers, wherein one of the auxiliary amplifiers is operated in it saturated region and the other is operated in its non-saturated region. The power amplifier and the two auxiliary amplifiers have the same distortion characteristics and receive the same input signal. The auxiliary amplifier operating in its saturated region introduces distortion and the auxiliary amplifier operating in its non-saturated region does not introduce distortion. The two signals provided by the auxiliary amplifiers are combined to produce an error signal having a distortion component that is an approximate replica of the power amplifier distortion.Type: GrantFiled: June 20, 2002Date of Patent: June 1, 2004Assignee: Harris CorporationInventors: Guang Fei Zhang, Xing Wang, Fabio Concilio, Tjo San Jao
