Document Type and Number:
WIPO Patent Application WO/2022/133819
Kind Code:
A1
Abstract:
An apparatus for proces sing radio frequency signals, comprising a first phase shifting stage configured to receive an RF signal and to provide n1 many, with n1 >= 2, phase-shifted portions of the RF signal, and at least a second phase shifting stage configured to receive the n1 many phase-shifted portions of the RF signal and to provide n2 many, with n2 >= n1, phase-shifted portions of the RF signal based on the received n1 many phase-shifted portions of the RF signal, wherein a phase shift applied by the second phase shifting stage to the n1 many phase-shifted portions of the RF signal is based on at least one phase shift applied by the first phase shifting stage to the n1 many phase-shifted portions of the RF signal with respect to the RF signal.
