Abstract
Wideband multiplexer for radio-frequency (RF) applications. In some embodiments, a multiplexer may include a common path configured to receive a plurality of RF signals. The multiplexer may further include a first path having an output coupled to the common path and configured to provide a band-pass response for a frequency band BX. The multiplexer may further include a second path having an output coupled to the common path such that RF signals in the first and second paths are combined and routed through the common path. The second path may be configured to provide a band-stop response for the frequency band BX such that the common path includes a wideband response that includes the frequency band BX and one or more other frequency bands.

A multiplexer for processing of radio-frequency (RF) signals, the multiplexer comprising:
- a common path configured to receive a plurality of radio-frequency signals;
- a first path having an output coupled to the common path and configured to provide a band-pass response for a first frequency band BX;
- and
- a second path having an output coupled to the common path such that radio-frequency signals in the first and second paths are combined and routed through the common path, the second path configured to provide a band-stop response for the first frequency band BX such that the common path includes a wideband response that includes the first frequency band BX and one or more other frequency bands, the second path including a resonant circuit configured to provide the band-stop response, the resonant circuit including an LC resonant circuit or a SAW (surface acoustic wave) resonant circuit.
A radio-frequency module comprising:
- a packaging substrate configured to receive a plurality of components;
- and
- a multiplexer implemented on or within the packaging substrate, the multiplexer including a common path configured to receive a plurality of radio-frequency signals, the multiplexer further including a first path having an output coupled to the common path and configured to provide a band-pass response for a first frequency band BX, the multiplexer further including a second path having an output coupled to the common path such that radio-frequency signals in the first and second paths are combined and routed through the common path, the second path configured to provide a band-stop response for the first frequency band BX such that the common path includes a wideband response that includes the first frequency band BX and one or more other frequency bands, the second path including a resonant circuit configured to provide the band-stop response, the resonant circuit including an LC resonant circuit or a SAW (surface acoustic wave) resonant circuit.
