| 20100166124 | DIGITAL ARCHITECTURE FOR RADIO-FREQUENCY APPARATUS AND ASSOCIATED METHODS - A radio-frequency (RF) receiver includes a receiver analog circuitry and a receiver digital circuitry. The receiver analog circuitry resides within a first integrated circuit and the receiver digital circuitry resides within a second integrated circuit. The second integrated circuit couples to the first integrated circuit via a one-bit digital interface. The receiver analog circuitry receives an RF signal and processes the received RF signal to generate a digital signal. The receiver analog circuitry provides the digital signal to the receiver digital circuitry. The receiver digital circuitry includes a digital down-converter circuitry that mixes the digital signal with an intermediate frequency (IF) local oscillator (LO) signal to generate a digital down-converted signal. The receiver digital circuitry also includes a digital filter circuitry that filters the digital down-converted signal to generate a filtered digital signal. | 07-01-2010 |
| 20100167684 | QUADRATURE SIGNAL GENERATION IN RADIO-FREQUENCY APPARATUS AND ASSOCIATED METHODS - A radio-frequency (RF) apparatus, which may reside in a receiver or transceiver, includes receive-path circuitry. The receive-path circuitry includes a poly-phase filter and a harmonic filter. The poly-phase filter accepts an input signal and generates two output signals. One output signal of the poly-phase filter constitutes an in-phase (I) signal. The other output signal of the poly-phase filter constitutes a quadrature (Q) signal. The a harmonic filter couples to the poly-phase filter. The harmonic filter accepts as input signals the in-phase and quadrature output signals of the poly-phase filter. | 07-01-2010 |
| 20100246995 | Method for Performing Dual Mode Image Rejection Calibration in a Receiver - A method is disclosed for performing dual mode image rejection calibration in a receiver. A first image correction factor is acquired using a first known signal associated with a first signal band during a startup mode. The first image correction factor has a plurality of bits including most significant bits (MSBs) and least significant bits (LSBs). The LSBs of the first image correction factor are adjusted incrementally during a normal operation mode. A radio frequency (RF) signal associated with the first signal band is received using the first image correction factor during the normal operation mode. | 09-30-2010 |
