摘要： An RF transmitter includes a Cartesian to polar conversion section, a PLL, a DAC module, a mixing module, and a PA module. The Cartesian to polar conversion section converts a Cartesian based symbol stream into a polar based symbol stream. The PLL generates an oscillation when the RF transmitter is in a Cartesian mode or a phase modulated oscillation based on phase modulation information of the polar based symbol stream when the RF transmitter is in a polar mode. The mixing module mixes an analog Cartesian based signal with a local oscillation to produce a Cartesian based up converted signal when the RF transmitter is in the Cartesian mode and mixes an analog amplitude signal with a phase modulated local oscillation to produce a polar based up converted signal when the RF transmitter is in the polar mode. The PA module amplifies the Cartesian based up converted signal to produce an outbound RF signal when the RF transmitter is in the Cartesian mode and amplifies the polar based up converted signal to produce the outbound RF signal when the RF transmitter is in the polar mode.

摘要： 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： Enhanced polar modulator for transmitter. Within a phase locked loop (PLL), a two point modulation topology is employed in which phase information passes through a limiter (e.g., a ±90° or ±π/2) in which the phase information dynamic range is divide by a factor (e.g., by 2) and a maximum frequency deviation is also divided by a factor (e.g., by 2). Then, a double balanced up-converter mixer/modulator is implemented to perform gain adjustment (e.g., magnitude and/or amplitude adjustment) and phase changes of 0° and +180° or 0 and +π (e.g., negative gains values may be employed). Phase adjustment in such an architecture is split and provided to both the PLL and to the mixer/modulator of such a polar modulator within a transmitter module such as may be implemented within a communication device (e.g., which may be a wireless communication device). This architecture that includes a PLL with a double balanced up-converter mixer/modulator suppresses even harmonics.
