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： Aspects of a method and system for an RF front-end calibration scheme using signals from a fractional-N frequency synthesized and received signal strength indicator (RSSI) are provided. A frequency synthesizer within a wireless receiver may generate a signal for dynamically modifying a gain in an integrated low-noise amplifier (LNA) for each selected receiver channel. The frequency-synthesized signals may be applied to at least one tunable load communicatively coupled to the LNA. The tunable load may be an input load or an output load. The signal generated by the frequency synthesizer may be sequentially applied to the input load and the output load. A logarithmic amplifier may generate an RSSI signal from the LNA output during the calibration process. The RSSI signal may be utilized for controlling a tunable load coupled to the LNA and optimize the tuning of the LNA in a desired channel by adjusting the tunable load.

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： 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.
