Abstract
A cascade comprising multiple filters according to an embodiment comprises a filter, which includes a splitter configured to split an analog radio-frequency input signal into at least a first signal and a second signal, a first signal path configured to generate, based on the first signal, a time-delayed signal delayed by a predetermined delay time in the time domain, a second signal path configured to generate, based on the second signal, a phase-shifted signal shifted by a controllable predetermined phase shift in the phase domain, and a coupler configured to generate an output signal based on the time-delayed signal and the phase-shifted signal. Using an embodiment may improve a trade-off between frequency-related flexibility and frequency agility of a receiver infrastructure.
