摘要： A bi-polar modulator that can perform quadrature modulation using amplitude modulators is described. In one design, the bi-polar modulator includes first and second amplitude modulators and a summer. The first amplitude modulator amplitude modulates a first carrier signal with a first input signal and provides a first amplitude modulated signal. The second amplitude modulator amplitude modulates a second carrier signal with a second input signal and provides a second amplitude modulated signal. The summer sums the first and second amplitude modulated signals and provides a quadrature modulated signal that is both amplitude and phase modulated. The first and second input signals may be obtained based on absolute values of first and second modulating signals, respectively. The first and second carrier signals have phases determined based on the sign of the first and second modulating signals, respectively. Each amplitude modulator may be implemented with a class-E amplifier.

摘要： A circuit receives a first signal (for example, a baseband signal) and mixes it with a local oscillator (LO) signal, and outputs a second signal (for example, an RFOUT signal). The circuit includes multiple identical Mixer and Frequency Divider Pair (MFDP) circuits. Each MFDP can be enabled separately. Each MFDP includes a mixer and a frequency divider that provides the mixer with a local version of the LO signal. The MFDP outputs are coupled together so that the output power of the second signal (RFOUT) is the combined output powers of the various MFDPs. By controlling the number of enabled MFDPs, the output power of the second signal is controlled. Because the MFDPs all have identical layouts, accuracy of output power step size is improved. Because LO signal power within the circuit automatically changes in proportion to the number of enabled MFDPs, local oscillator leakage problems are avoided.

摘要： An apparatus comprising a programmable frequency device adapted to generate a reference clock selected from a set of distinct frequency clocks, wherein the programmable frequency device is further adapted to maintain the same temporal relationship of the triggering edges of the reference clock when switching between the distinct frequency clocks. The apparatus further comprises a phase locked loop (PLL), such as a digital PLL (DPLL), that uses the selected reference clock to establish a predetermined phase relationship between an input signal and an output signal. By maintaining substantially the same temporal relationship of the reference clock when switching between distinct frequency clocks, the continual and effective operation of the phase locked loop (PLL) is not significantly disturbed while changing the reference clock. This may be used to control the power consumption of the apparatus.

摘要： Transmitters supporting multiple modulation modes and/or multiple frequency bands are described. A transmitter may perform large signal polar modulation, small signal polar modulation, and/or quadrature modulation, which may support different modulation schemes and systems. Circuit blocks may be shared by the different modulation modes to reduce cost and power. For example, a single modulator (160) and a single power amplifier (170) may be used for small signal polar modulation and quadrature modulation. The transmitter may apply pre-distortion (124,142) to improve performance, to allow a power amplifier to support multiple frequency bands, to allow the power amplifier to operate at higher output power levels, etc. Envelope and phase distortions due to non-linearity of the power amplifier may be characterized for different input levels and different bands and stored at the transmitter. Thereafter, envelope and phase signals may be pre-distorted based on the stored characterizations to compensate for non-linearity of the power amplifier.
