Abstract
Various embodiments are directed to removing interfering signals in a broadband radio frequency (RF) receiver by implementing a silicon tuner arranged to replicate high quality factor (Q) performance without the advantages of using high Q components available for module tuners. In one or more embodiments, tuned filter elements within a broadband silicon tuner are reused to maximize the attenuation of unwanted signals while minimizing induced undesirable channel ripple. In various implementations, a number of tuned passive inductor/capacitor filter elements are combined as required such that filter elements for an unused frequency band are reconfigured to provide attenuation of and enhanced immunity to unwanted signals. Other embodiments are described and claimed.
