Abstract

A multiple frequency band receiver (,) receives at least two frequency bands that are close but not adjacent. A first bandpass filter (,) passes signals in the first frequency band. A second bandpass filter (,) passes signals in the second frequency band. The first and second filters each attenuate signals between the first and second frequency band to at least a first level so as to provide selectivity in the frequency range between the first and second frequencies to prevent the signals between these frequency bands from being further processed by the communication device. A third filter (,) coupled to first and second filters passes signals in both the first and second frequency band and attenuates signals above the pass band of the higher of the first and second filters and below the lower of the first and second filters.
