摘要： Methods and systems for a variable system on demand are disclosed. Aspects of the method may include configuring one or more filters in a wireless transmitter and/or receiver for a desired band and standard. The presence of a blocker signal in a receiver may be known and/or determined and the receiver may be configured for mitigating the blocker signal. A desired received signal strength indicator may be compared to a wideband received signal strength indicator. Gain levels may be configured in the receiver based on the comparison. Linearity of the receiver may be configured for blocker signal mitigation. The filters may include baseband filters and/or may be at an output of the receiver. The filters may include a plurality of stages, with one or more of the stages bypassed for filter configuring, and may include a mixer as an input. Capacitors and/or resistors may be configured in the filters.

摘要： Wideband-Code Division Multiple Access (W-CDMA) transmit architecture. A baseband digital processing module operates cooperatively with an analog signal processing module to effectuate highly adjustable and highly accurate gain adjustment in accordance with transmitter processing within a communication device. The gain adjustment and/or gain control is partitioned between the digital and analog domains by employing two cooperatively operating digital and analog modules, respectively. Gain adjustment in the analog domain is performed in a relatively more coarse fashion that in the digital domain. If desired, gain adjustment in each of the analog and digital domains is performed across a range of discrete steps. The discrete steps in the analog domain are larger than the discrete steps in the digital domain. Also, the discrete steps in the digital domain may be interposed between two successive discrete steps in the analog domain.

摘要： An integrated circuit (IC) includes a receiver module, a transmitter module, an inbound digital module, and a local oscillation generation module. The receiver module is operable to convert an inbound high frequency signal into a down converted inbound signal based on a receive local oscillation independently of a protocol of the inbound high frequency signal. The inbound digital module is coupled to compensate the down converted inbound signal in accordance with a selected one of the first plurality of wireless communication protocols. The transmitter module is operable to convert a first outbound signal into a first up converted signal based on a transmit local oscillation when a first one of the first plurality of wireless communication protocols is active and to convert a second outbound signal into a second up converted signal based on the transmit local oscillation when a second one of the first plurality of wireless communication protocols is active.

摘要： A method and system for filter calibration using fractional-N frequency synthesized signals are presented. Aspects of the method may include generating an LO signal by a PLL circuit within a chip. A reference signal may be generated based on the generated LO signal and a synthesizer control signal. A frequency response for a filter circuit integrated within the chip may be calibrated by adjusting parameters associated with the filter circuit based on the generated LO signal. Aspects of the system may include a single-chip multi-band RF receiver that enables generation of a LO signal by a PLL circuit within the single-chip, and enables calibration of a frequency response for a filter circuit integrated within the chip. A reference signal may be generated based on the generated LO signal and a synthesizer control signal. The frequency response may be calibrated by adjusting the filter based on the generated reference signal.

摘要： Aspects of a method and system for a multi-band direct conversion CMOS mobile television tuner are provided. A single-chip multi-band RF receiver in a mobile terminal comprising UHF and L-band front-ends receives and amplifies an RF signal utilizing an LNA integrated into the front-end that corresponds to the type of signal received. A received signal strength indicator (RSSI) value may be determined for the amplified signal within the single-chip receiver and may be utilized to adjust a gain of the LNA. The adjustment may be made via on-chip or off-chip processing of the RSSI value. The single-chip receiver may directly convert the amplified signal to a baseband frequency signal and generate in-phase and quadrature components. The components of the baseband frequency signal may be filtered and/or amplified via programmable devices within the single-chip receiver. Circuitry within the single-chip receiver may be controller via an on-chip digital interface.
