摘要： A quadrature combiner circuit is provided which employs a quadrature coupler to split an input radio frequency signal into split radio frequency signals which are amplified by respective amplifiers and recombined in a second quadrature coupler in such a manner as to minimize intermodulation distortion products. A feedback loop is employed to assure that the split amplified radio frequency signals incident upon the second quadrature combiner are maintained in quadrature relationship to assure intermodulation product cancellation.

摘要： A transmitter is provided with a local oscillator (LO) processing unit to maintain stability in the transmitter's feedback loop. The LO processing unit includes at least one delay locked loop (DLL) and a programmable divider to generate phase shifted LO signals for adjusting a loop phase of the feedback loop in the transmitter. The generated phase shifted LO signals are of both a coarse and fine phase shifted nature. The adjustability and control of the coarse and fine phase shifting of the LO signals maintains linearity in the transmitter feedback loop.

摘要： A frequency synthesizer includes: a frequency source generating a reference signal that includes a plurality of pulses having periodicity based on a reference frequency; a feedback loop that includes, a phase detector circuit, a loop filter, a controlled oscillator that generates an output signal at an output, and a loop divide circuit; a non-linear circuit element at an input of the phase detector circuit, which generates intermodulation distortion that causes at least one spurious signal at the output; and a controller controlling the loop divide circuit and the non-linear circuit element. The frequency synthesizer further includes a dither circuit that adjusts the timing of some of the pulses of the reference signal based on a parameter provided by the controller to the non-linear circuit element, thereby, providing a jittered reference signal to the non-linear circuit element for attenuating the at least one spurious signal at the output.

摘要： A method and apparatus for reducing in-band spurs in a fractional-N synthesizer (100) includes generating a compensated current signal by a charge pump (108) coupled to a phase detector (106). The compensated current signal includes in-band spurs having frequencies within a frequency bandwidth associated with a loop filter (110). The method then includes selectively dithering the compensated current signal with a sufficient dither level to spread the frequencies of in-band spurs beyond the frequency bandwidth associated with the loop filter (110). The dithered compensated current signal is then passed through the loop filter (110) for filtering the in-band spurs having frequencies beyond the frequency bandwidth. The method then includes generating a voltage controlled oscillator (VCO) signal with reduced in-band spurs proportional to the filtered compensated current signal.

摘要： A method and apparatus is provided that amplitude modulates a modulated radio frequency (RF) signal (411) by modulating the supply voltage of a power amplifier (410). The method and apparatus further provides an impedance modulator (412) that reduces output signal (415) errors in response to an error signal generated by a feedback circuit (416) that includes a quadrature modulator (506), a limiter (520), a comparator (502), and a quadrature downconverter (510). Intermodulation distortion generated in the feedback circuit (416) by delay mismatches between amplitude and phase feedback paths, and non-linear effects of AM/PM conversion in a limiter (520), are suppressed by placing limiter (520) and quadrature downconverter (510) in a forward path of the overall amplifier loop.

摘要： An amplifier level-setting apparatus is provided for obtaining the maximum power output and highest efficiency allowable for a predetermined level of distortion. According to the invention, a training signal is applied to the input of the amplifier prior to the desired signal. The training signal level is increased while the output distortion is measured. When the output distortion level reaches a predetermined limit, the corresponding training signal input level is saved. The input signal level is then adjusted to this saved level value, thereby resulting in the maximum amplifier output level possible that is still within the distortion limit.

摘要： Apparatus is provided for inhibiting the generation of intermodulation products in a radio frequency amplifier coupled to a circulator. A control circuit generates a control signal exhibiting indicia of the amount of isolation provided by the circulator. The control signal is provided to a variable impedance synthesis circuit coupled to the circulation isolation port such that the impedance synthesis circuit exhibits the appropriate impedance to maximize circulation isolation. Intermodulation is thus minimized.
