摘要： The invention relates to a millimetre frequency oscillator using integrated circuit technology. The oscillator comprises a microwave output (Sf) providing an oscillation frequency Fout dependent on a control signal Vt. The oscillation frequency Fout can be modulated around a central frequency Fc via two control inputs of the oscillator, a first control input Ec1 fed with a first control signal Vt1 fixing the central frequency Fc of the oscillator and a second control input Ec2 fed with a second control signal Vt2 allowing the linear modulation of this central frequency Fc. The control signal Vt of the oscillator is a function of the two control signals Vt1 and Vt2. Application: telecommunications, radar, radar for motorcars.

摘要： A method of compensating delay in a linearization loop of a power amplifier and a linearization arrangement of a power amplifier, which arrangement comprises an I/Q modulator (10), one or more power amplifiers (13) to be linearized and generating delay, and a feedback loop comprising an I/Q demodulator (11) when the I/Q modulator (10) and the I/Q demodulator (11) derive an oscillator frequency from the same local oscillator (14). In accordance with the invention, the delay generated by the power amplifier in the feedback is compensated by delaying a local oscillator signal applied to the I/Q demodulator (11). The delay of the local oscillator signal applied to the I/Q demodulator (11) is generated by an amplifier optimized to have a great delay, preferably by a small-signal amplifier.

摘要： This invention teaches methods and apparatus for providing a low cost, low complexity, and low component count transmitter feedback function for use in mobile station transmitter linearization and self-test operations. Disclosed is a method for operating a mobile station of a type that includes a transmit chain having an output coupled to an antenna and a receive chain having an input coupled to the same or a different antenna. The method includes steps of: during a transmission time, (a) sampling an amplified signal prior to the amplified signal being applied to the antenna for transmission from the transmit chain; (b) downconverting a frequency of the sampled amplified signal to a lower frequency signal using a receive chain local oscillator signal normally used for downconverting a received signal to the first IF; and (c) demodulating the lower frequency signal to a baseband signal with a receive chain demodulator by using a second local oscillator signal that is normally used as a transmit chain modulator injection frequency signal. A further step of the method determines from the baseband signal an amount of predistortion of an input signal to the transmit chain in order to obtain a desired amount of linearization of the amplified signal.

摘要： A linear transmitter (10) having both an open loop and a closed loop training mode capability functions to schedule and facilitate these training modes in a manner that reduces adjacent channel splatter. A training waveform can be utilized to enhance these operational objectives. Scheduling of the open loop and closed loop training modes can be ordered, in a TDM system, in a variety of ways. Transmitter (10) includes first and second information paths (11 and 12), a combined information signal path (13), first and second feedback paths (14 and 15) and a phase adjustment unit (16).

摘要： In a method for generating a transmitting wave, a power supply voltage (Vcc) to be supplied to a transmission power amplifier (3) is detected by a voltage detector (11), and a modulating signal (Sm) is controlled so that a peak value of a modulated wave (St) is lowered in accordance with a reduction amount of the power supply voltage (Vcc). Since the peak value of the modulated wave input to the power amplifier (3) is lowered, it is possible to obtain a transmitting wave without a distortion of the wave form or an increased bandwidth even when the reduction in the power supply voltage involves the lowering of the driving capability of the power amplifier.

摘要： A modulation system responsive to a sampled signal (31) of a sampling rate for supplying a modulated analog signal to an amplifier having nonlinearities to make the amplifier produce an amplified output signal, in which a processing arrangement (36) processes the signal with reference to a difference between the signal and an additional digital signal (35) to compensate for the nonlinearities to produce a processed signal. The processed signal is modulated into the modulated analog signal. The amplified output signal is demodulated and converted into the additional digital signal by a converter (40). Otherwise, the second control signal is produced. A controller (78) may control a phase of a sampling signal supplied to the converter so that a quotient of the difference by a differential of the selected signal becomes equal to zero.
