Abstract:
1. A frequency divider arrangement for providing a quadrature output signal comprising a quadrature output signal frequency, comprising: a signal source configured to provide a base signal having a base signal frequency; a first integer number quadrature divider with a first divider ratio configured to receive the base signal and provide a first quadrature signal having a first quadrature signal frequency according to the first divider ratio of the first integer number quadrature divider; a quadrature mixer arrangement configured to provide a quadrature mixer output signal at the output side based on a mixing of a first quadrature mixer input signal and a second quadrature mixer input signal, wherein the first quadrature mixer input signal corresponds to the first quadrature signal; and an integer number quadrature divider arrangement comprising a second integer number quadrature divider with a second divider ratio configured to receive the quadrature mixer output signal or a signal comprising a same frequency derived from the quadrature mixer output signal and provide the second quadrature mixer input signal and the quadrature output signal that are divided, unmixed versions of the quadrature mixer output signal, wherein the second quadrature mixer input signal is derived from the quadrature output signal or corresponds to the quadrature output signal.
