摘要： Radio-frequency (RF) apparatus includes receiver analog circuitry that receives an RF signal and provides at least one digital signal to receiver digital circuitry that functions in cooperation with the receiver analog circuitry. The receiver analog circuitry and the receiver digital circuitry are partitioned so that interference effects between the receiver analog circuitry and the receiver digital circuitry tend to be reduced.

摘要： Interchangeable high band low-noise-amplifiers (LNAs) and low band low-noise-amplifiers (LNAs) and related methods are disclosed that greatly enhance the efficiency of designing handsets for different combinations of frequency bands. The input signals to particular pins on a receiver or transceiver integrated circuit (IC) are swappable such that multiple frequency bands can be input to the same input pins thereby allowing for simplified system design. Efficient programmable techniques are also disclosed for controlling a swap mode within communication ICs. These interchangeable or band swappable input paths, for example, can be utilized to allow interchangeability between high band (PCS, DCS) and low band (GSM, E-GSM) inputs for cellular communications. In this way, for example, handset manufacturers can build a single printed circuit board (PCB) that can be utilized for cellular communications in the United States of America, where 850 MHz (GSM) and 1900 MHz (PCS) bands are utilized, and in Europe, wherein 900 MHz (E-GSM) and 1800 MHz (DCS) bands are utilized.

摘要： Components of a radio-frequency (RF) apparatus including transceiver circuitry and frequency modification circuitry of a crystal oscillator circuit that generates a reference signal with adjustable frequency may be partitioned in a variety of ways, for example, as one or more separate integrated circuits. The frequency modification circuitry may be implemented as part of a crystal oscillator circuit that includes digitally controlled crystal oscillator (“DCXO”) circuitry and a crystal. The frequency modification circuitry may include at least one variable capacitance device and may be employed to generate a reference signal with adjustable frequency. The adjustable reference signal may be provided to other components of the RF apparatus and/or the RF apparatus may be configured to provide the adjustable reference signal to baseband processor circuitry. Automatic frequency control (AFC) circuitry may be integrated with other components of RF circuitry and may generate frequency control signals for the frequency modification circuitry based on, for example, a signal received from a temperature sensor. Digital-to-analog converter (DAC) circuitry may be integrated with other components of RF circuitry to enable all-digital frequency control communications from baseband processor circuitry to RF circuitry.

摘要： On-chip calibration signal generation circuitry is disclosed for filter tuning for radio-frequency communications and associated methods. On-chip circuitry generates a calibration signal that is used to help set a tuning control signal that is received by a tunable front-end filter. In one embodiment, local oscillator (LO) generation circuitry is used to generate the calibration signal. In operation of this embodiment, the LO generation circuitry is tuned to the desired receive channel, or to a frequency at some offset value from the desired receive channel, and the output of the LO generation circuitry is then used as a calibration input signal for a tunable front-end filter. This calibration signal is passed through the receive path circuitry, and the resulting signal is then analyzed to help set a tuning control signal for the tunable front-end filter.
