Abstract
Architectures and techniques relate to ganged and switch combined systems for satellite-navigation-band filters. For example, a system can include a mid-range-band filter, a satellite-navigation-band filter, and circuitry configured to receive a signal from an antenna and route the signal to the mid-range-band filter and the satellite-navigation-band filter. The circuitry can be implemented in at least one of (i) a ganged configuration in which the mid-range-band filter and the satellite-navigation-band filter receive the signal through a common input node or (ii) a switch-combined configuration in which two or more switch arms are configured to be controlled simultaneously to route the signal to the mid-range-band filter and the satellite-navigation-band filter.
Claims20
A filter circuit comprising:
- a switch configured to receive a signal;
- a first mid-range-band filter configured to support a first cellular band for receive operations;
- a second mid-range-band filter configured to support a second cellular band;
- a first satellite-navigation-band filter;
- and
- circuitry configured to route the signal, the circuitry being implemented in at least one of (i) a ganged configuration in which the switch is used to select between a first path associated with routing the signal to the first satellite-navigation-band filter and the first mid-range-band filter via a first common input node or a second path associated with routing the signal to a second satellite-navigation-band filter and the second mid-range-band filter via a second common input node or (ii) a switch-combined configuration in which the switch includes two or more switch arms that are configured to be controlled simultaneously to route the signal to the first satellite-navigation-band filter and a single one of the first mid-range-band filter or the second mid-range-band filter.
A filter system comprising:
- a first switch configured to receive a signal;
- a first filter coupled to the first switch and configured to support a first cellular band;
- and
- a second filter coupled to the first switch and configured to support a second cellular band, the filter system being configured to route the signal to a first satellite-navigation-band filter or a second satellite-navigation-band filter and use the first switch to selectively route the signal to either the first filter or the second filter, the filter system including at least one of the first switch implemented with two or more simultaneously-controllable arms or a common input node for the first satellite-navigation-band filter and the first filter.
A radio-frequency module comprising:
- a packaging substrate;
- a multiplexer implemented on the packaging substrate and coupled to at least one of a primary antenna or a diversity antenna;
- and
- a filter system implemented on the packaging substrate and coupled to the multiplexer, the filter system including a first mid-range-band filter, a second mid-range-band filter, a satellite-navigation-band filter, and a switch, the filter system being configured to receive a signal from the multiplexer and route the signal, using the switch, to the satellite-navigation-band filter and a selected one of the first mid-range-band filter or the second mid-range-band filter, the filter system including at least one of the switch implemented with two or more simultaneously-controllable arms or a common input node for the satellite-navigation-band filter and the first mid-range-band filter.
