摘要： A method is provided for generating a multiple band ultrawide bandwidth signal. In this method, an ultrawide bandwidth devices provides a first reference signal having a first reference frequency, and a second reference signal having a second reference frequency that is different from the first reference frequency. The device generates a first ultrawide bandwidth signal based on the first reference signal, and a second ultrawide bandwidth signal based on the second reference signal, creating two separate frequency bands. These two signals can be generated form the same base clock signal, allowing for significantly simpler implementation and modification.

摘要： A quadrature bandpass-sampling analog-to-digital demodulator (QBS-ADD) is provided. A radio frequency (RF) signal is received by a junction summer, which subtracts an in-phase feedback signal and a quadrature feedback signal from the RF signal to produce an error signal. The error signal is then bandpassed and amplified by the RF bandpass filter/amplifier. The amplified signal is bandpass-sampled by two low-resolution analog-to-digital converters clocking in quadrature, and is demodulated and converted into a digital in-phase signal and a digital quadrature signal. The down converted in-phase and quadrature signals are multiplied with two quadrature clocks. The results are converted to two analog signals and fed back to the RF input at the junction summer.
