Abstract

A radio frequency front-end circuit includes a first diplexer, an extractor, and a second diplexer. First diplexer is coupled to an antenna for receiving a radio frequency signal and configured to separate radio frequency signal into a first signal within low, mid andhigh bands of a wireless wide area network and a second signal within an ultra-high band of WWAN. Extractor is coupled to first diplexer. Extractor includes two band pass filters and a band rejection filter. Two band pass filters are configured to extract two global navigation system signals within two global navigation system bands from first signal. Band rejection filter is configured to allow a third signal within the mid and high bands of WWAN in first signal to pass. Second diplexer is coupled to first diplexer and extractor and configured to combine second and third signals into a WWAN signal.
