Patent number: 8311156Abstract: A receiver configured to selectively receive an RF signal from an operating band having a plurality of RF channels. The receiver is configured to upconvert the desired RF channel to an intermediate frequency (IF) greater than the RF channel frequencies. The upconverted RF channel is downconverted to baseband or a low IF. The receiver can perform channel selection by filtering the baseband or low IF signal. The baseband or low IF signal can be upconverted to a programmable output IF.Type: GrantFiled: July 6, 2010Date of Patent: November 13, 2012Assignee: MaxLinear, Inc.Inventors: Kishore Seendripu, Raymond Montemayor, Sheng Ye, Glenn Chang, Curtis Ling

Patent number: 8306157Abstract: A receiver can be configured to include an RF front end that is configured to downconvert a received signal to a baseband signal or a low Intermediate Frequency (IF) signal. The receiver can downconvert the desired signal from an RF frequency in the presence of numerous interference sources to a baseband or low IF signal for filtering and channel selection. The filtered baseband or low IF signal can be converted to a digital representation. The digital representation of the signal can be upconverted in the digital domain to a programmable IF frequency. The digital IF signal can be converted to an analog IF signal that can be processed by legacy hardware.Type: GrantFiled: July 6, 2010Date of Patent: November 6, 2012Assignee: Maxlinear, Inc.Inventors: Kishore Seendripu, Raymond Montemayor, Sheng Ye, Glenn Chang, Curtis Ling

Patent number: 7917091Abstract: Methods and apparatus for calibrating In-phase and Quadrature imbalance within a receiver are described. A calibration process can inject a calibration tone to an RF or IF portion of a receiver. The receiver can frequency translate the tone to distinct I and Q calibration signals. The receiver upconverts the I and Q calibration signals to complementary sidebands or images using distinct and substantially matched upconverters. The complementary sidebands are mixed together to generate an error signal. The receiver determines a phase and amplitude correction based on the error signal.Type: GrantFiled: June 28, 2007Date of Patent: March 29, 2011Assignee: MaxLinear, Inc.Inventors: Raymond Montemayor, Sheng Ye
