摘要： A linearizer reduces nonlinear intermodulation distortion in radio frequency and microwave systems by first directly generating in-phase and quadrature nonlinear intermodulation products of the system input. Controllable amounts of each phase are then added back into the system such that the vector sum of nonlinear intermodulation products at the output is reduced or eliminated by destructive interference, while the fundamentals are substantially unaffected. The quadrature distorted signals are generated with two lightly-biased and thus overdriven differential pairs having gain-determining degeneration impedances that are in quadrature with each other. The amount of each quadrature phase summed to the output is controlled with electronically tunable four-quadrant variable attenuators. The quadrature phasing enables rapidly convergent tuning to minimize distortion using conventional scalar spectral analysis. The advantages of a linearizer using rectangular vector coordinate system are significant.

摘要： A stabilized quadrature RC/CR phase shifting network for generating quadrature RF and microwave signals. The network uses offset biasing of postamplifiers following the phaseshifter to fine tune quadrature-phase, and further uses an output quadrature-phase detector to stabilize quadrature-phase with negative feedback by using the quadrature-phase error signal to drive the quadrature-phase fine tuning control. In an alternative embodiment, the stability of quadrature-phase can be enhanced without the output quadrature-phase detector by making the quadrature-phase fine tuning control dependent upon the amplitude-difference negative feedback error signal.

摘要： An IQ modulator incorporates a quadrature network that is responsive to a frequency dependent control signal and that has in-phase and quadrature signals that are of equal amplitude and in exact quadrature over a wide range of applied frequencies. The quadrature network includes RC and CR phase shifters whose C's are fixed capacitors of equal value and whose R's are made equal to each other and to the capacitive reactance of the C's by the action of the frequency dependent control signal. The R's may be FET's. The frequency dependent control signal may be generated without express knowledge of the applied frequency by a servo loop that nulls out the amplitude difference between the in-phase and quadrature outputs from the quadrature network; it may also be generated from a look-up table as an express function of frequency. The frequency dependent control signal is split into separate instances that are applied to each R, and an offset may be introduced therebetween to provide extreme precision. The offset may be fixed or programmatically controlled as a function of frequency. Varactors may be used to provide variable C's in cooperation with fixed R's. The entire circuit may be fabricated as a GaAs IC for use in the frequency range of 200 MHz to 3GHz.
