摘要： Disclosed is a system and method for compensating for the effects of aging and temperature on the performance of transistors in an RF transmitter. The system and method use a temperature-based polynomial and a feedback control loop to correlate the drain current of each transistor with the desired performance characteristics of each transistor. The present invention measures drain current and temperature of the transistor; compares the measured drain current with the desired drain current, which corresponds to the desired performance characteristics; computes a transistor bias voltage based on the temperature and a control parameter, wherein the control parameter is adjustable based on the measured drain current; and applies the bias voltage to the transistor. The process may be repeated, with the control parameter adjusted with each iteration, until the desired drain current is reached.

摘要： Systems and methods for reducing interference in an enhanced radio receiver from a transmitter when both are located in the same aircraft are provided. The enhanced radio receiver detects and attenuates a signal from the transmitter, without attenuation or interference with other desired signals. An enhanced radio transmitter may inform the enhanced radio receiver of the frequency of transmission via a data communication path such that the enhanced radio receiver attenuates the transmitted frequency for the duration of transmission.

摘要： Signal processing systems for radar installations are provided for simultaneous processing of one or more IF signals of dynamically varying frequency and bandwidth with a single analog signal path. The signal processing system includes, but is not limited to, a converter configured to digitize a return signal resulting in a digitized broadband signal, and a signal processor coupled to the converter. The signal processor includes a digital filter having a center frequency and a bandwidth, and the digital filter is configured to select a signal from the digitized broadband signal. The selected signal has a center frequency. The signal processor is configured to match the center frequency of the digital filter with the center frequency of the selected signal, and adjust the bandwidth of the digital filter based on the selected signal.
