摘要： A Ku-band integrated pre-distortion type linearizer bridge circuit for use in linearizing the performance of a traveling wave tube amplifier. The linearizer bridge circuit comprises linearizer bridge that embodies a phase shifter and a fixed delay in a linear arm, and a Schottky diode distortion generator and a PIN diode attenuator in a nonlinear arm. The output of the linearizer bridge is coupled through an output amplifier and an output attenuator. The RF output signal from the linearizer bridge circuit is coupled to the traveling wave tube amplifier. A control circuit is coupled to the phase shifter, the nonlinear Schottky diode distortion generator circuit, and the PIN diode attenuator, and receives on and off input command signals, and outputs a bilevel telemetry signal that is used as a mode indicator for ground command control. The control circuit is used to adjust settings of the Schottky diode distortion generator, the phase shifter, the PIN diode attenuator, and adjust the gain and attenuation settings of the output amplifier and output attenuator. All circuits of the linearizer bridge circuit are integrated onto a single alumina substrate.

摘要： A circuit is provided for suppression of second-order intermodulation in a double-balanced mixer circuit. The circuit includes a duplicate transconductor element for duplicating AC current in a transconductor pair of the double-balanced mixer circuit. A fundamental cancellation element cancels a fundamental component of an AC current of the duplicate transconductor element, while preserving a second-order intermodulation component. A phase inversion element feeds an output current of the fundamental cancellation element to the transconductor pair of the double-balanced mixer circuit, to substantially remove the second-order intermodulation component from a differential output of the double-balanced mixer circuit.

摘要： A plurality of monitoring devices are arranged at different heights and steps, and infrared reflective assemblies of the monitoring device are set at different heights to collect infrared spectral data of chemical constituents of the air mass that are being diffused in airspace of different heights. The pollution factors contained in the air mass and the pollution level of each factor are learned by using IR spectrum for qualitative and quantitative analysis on the pollution factor, therefore realizing continuous monitoring in a certain area. Artificial duty is not required while 24-hour continuous intelligent monitoring can be achieved. Besides, meteorological data are collected in combination with the meteorological data collected by the meteorological information acquisition module at different heights and calculation is made based on the air diffusion model of various pollution factors to finally determine the position of air pollution source.

摘要： A device and method for canceling or attenuating harmonics noise without distorting the incoming signal. An exemplary device includes the use of an estimation loop to generate an artificial signal to eliminate or attenuate the influence of harmonics. The estimation loop includes a mixer adapted to produce a mixed signal by processing or combining the incoming signal and the artificial signal. The estimation loop includes an error detector, a low-pass filter, a parameter estimator, and a numerically controlled oscillator. The parameter estimator produces information relating to the phase, frequency, and amplitude of an incoming harmonics spur and will be used by the numerically controlled oscillator to generate the artificial signal. If the mixed signal contains relatively low levels of harmonics residuals, the mixed signal is produced at the output in lieu of the incoming signal.
