摘要： Method and apparatus for configuring a transmitter circuit to support linear or polar mode. In the linear mode, a baseband signal is specified by adjusting the amplitudes of in-phase (I) and quadrature (Q) signals, while in the polar mode, the information signal is specified by adjusting the phase of a local oscillator (LO) signal and the amplitude of either an I or a Q signal. In an exemplary embodiment, two mixers are provided for both linear and polar mode, with a set of switches selecting the appropriate input signals provided to one of the mixers based on whether the device is operating in linear or polar mode. In an exemplary embodiment, each mixer may be implemented using a scalable architecture that efficiently adjusts mixer size based on required transmit power.

摘要： An RF transmitter uses two digital-to-RF conversion modules to convert digital baseband signals into RF signals. In cartesian mode, baseband signals are conveyed to the conversion modules for RF conversion. In polar mode, baseband signals are converted into amplitude and phase data parts. Phase data part is converted into I and Q data parts to be converted by the conversion modules into RF signals, which are modulated in a power amplifier by amplitude data part through the power supply of the power amplifier. Each digital-to-RF module uses parallel unit cells to perform D/A conversion function and upconversion function by an IF signal. Each unit cell, adapted to receive a control voltage indicative of a data signal value, is a mixer cell type converter having a differential data switch section connected in series to a differential LO-switch pair. LO-switch is further connected in series to a current source.

摘要： The number of measurements needed to calibrat4e an electrical device is reduced. Apparatus and methods minimize output of one or more unwanted signals by determining a calibration setting, in a minimal number of measurements, from determined distances to a best setting. Each distance to a best setting can be determined as a function of the characteristic of the unwanted signal and the measured unwanted signal level. A calibration setting point can be determined by searching for a setting point having a lowest sum of distance errors determined from the calculated distances and from the measured and non measured setting points. The techniques and apparatus are useful for minimizing a number of measurements that would be needed for determining a setting that substantially prevents generation of unwanted output signals, such as carrier leakage (LO-leakage) and unwanted sidebands, and for quickly determining whether an acceptable calibration setting exists for a device.

摘要： Coherent modulator architectures of wireless communication devices are used for the processing of modulated RF signals. The circuitry comprises a DC/DC converter (204) which serves as an amplitude modulator, different amplification stages (204, 206, 212, 214), a bypass path (215) to selectively bypass at least one (214) of a cascade of class C, D, E, or F power amplifiers (212, 214), and an automatic power control (APC) loop (220) that guarantees power stability over time and temperature variations. To increase the efficiency of the amplification procedures needed for an amplitude modulation, the slow (narrowband) high-level components (222) and the fast (wideband) low-level components (224) of the signal representing the magnitude (I x Lp (t) l) of an I/Q modulation state (x Lp (t)) are amplified in separate stages (204, 206) and are then combined by sup plying the low-level components (224) to a power amplifier (206) whose gain is controlled depending on the amplified high-level components (222). At least one (214) of said cas cade of power amplifiers (212, 214) can selectively be bypassed by a bypass circuitry (215), which is used for the sake of efficiency optimization. In the bypass mode, the DC power supply (V bat ) of the bypassed power amplifier (214) can selectively be switched off by means of a switch (SZ) . It is used when the needed RF signal power is low and the driver PA (212) is able to produce enough gain.

摘要： Pseudo-noise (PN) carrier suppression up-converter and pseudo-noise image sideband rejection up-converter and down-converter circuits are provided. The image sideband rejection circuits enable the use of single step up-conversion without the need for the high Q filters associated with two-step up-conversion architectures. For carrier suppression, the frequency spectrum of an input signal is PSK (BPSK or QPSK) spread by a PN signal and the spread signal is up-converted using a PSK (BPSK or QPSK) modulated carrier (local oscillator) modulated by the same PN sequence. In an up-converter, a carrier is QPSK modulated using independent PN sequences and the frequency spectrum of the input signal is QPSK spread using the same independent PN sequences whereby image sideband rejection results upon up-converting the QPSK spread signal in a mixer using the QPSK modulated carrier. In a down-converter, a carrier signal which is QPSK modulated by independent PN sequences is used to down-convert an input signal in a mixer and the resulting down-converted signal is QPSK spread using the same independent PN sequences whereby image sideband rejection occurs.
