Abstract:
1. A method for converting a wide portion of a received RF signal into an IF signal, said method comprising: processing said RF signal in continuous fashion, wherein said processing said RF signal comprises bandpass filtering said RF signal with a filter comprising a switched filter structure with analog trim; frequency translating said processed RF signal to a low IF signal, said low IF signal comprising an in-phase component and a quadrature component; lowpass filtering the in-phase and quadrature components of said low IF signal; frequency translating each of said in-phase and quadrature components of said low IF signal to a high IF signal having in-phase and quadrature components; combining the frequency translated in-phase and quadrature components of said high IF signal; and filtering said combined high IF signal to yield an output IF signal.
