摘要： Line driver arrangement comprising a class-D switching amplifier having a switching frequency for receiving an input transmit signal and outputting an amplified transmit signal and a transformer having a predetermined leakage inductance for receiving the amplified transmit signal and outputting a transform signal as an output transmit signal. The leakage inductance is predetermined for low-pass filtering of the amplified transmit signal. The line driver arrangement reduces the number of additional discrete inductances, capacitances and or resistor for forming low-pass filters significantly. The inventive line driver arrangement is particularly power-efficient due to the included class-D switching amplifier. The predetermined leakage inductance leads to a suppression of a resonance due to the switching frequency of the class-D amplifier in the power spectral density. Hence, the inventive line driver arrangement complies at least with the ADSL PSD mask requirements.

摘要： This system and method provides a direction finding system that enables modern RF DF systems to analyze short duration signals in the entire instantaneous bandwidth. By providing a method to process wideband data, the invention drastically improves throughput and probability of intercept (POI). The invention is unique in that it does not require separate narrowband channels for analysis, and can simultaneously calculate azimuth and elevation estimates for every frequency in the bandwidth of an incident signal. It is also well-suited for fixed point, FPGA implementations making it a perfect match for modern state-of-the-art processing systems. The system and method capitalizes on the ability of Fourier Frequency Transform operations to accurately resolve incident wave phase at discrete frequencies. The system then uses the phase information from the individual elements in the array to arrive at an emitter azimuth angle. The azimuth angle is nearly simultaneously used in concert with lookup tables of all possible elevation angles to compare the arrival time delay between the array elements to determine emitter elevation angle.
