ABSTRACT:
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.
