Abstract
Multiplexers having hybrid circuits with resonators. In some embodiments, a multiplexer for processing radio-frequency signals can include a plurality of nodes, a common node, and a signal path implemented between each of the plurality of nodes and the common node. Each signal path can include a filter, and each of at least some of the signal paths can further include a resonator coupled with the corresponding filter. A signal path with the resonator provides a sharper notch profile for a radio-frequency signal than a signal path without the resonator.
Claims19
A multiplexer for processing radio-frequency signals, comprising:
- a plurality of nodes;
- a common node;
- and
- a signal path implemented between each of the plurality of nodes and the common node, each corresponding signal path including a filter and a respective resonator, the plurality of corresponding signal paths configured to support carrier aggregation of respective signals through the common node.
A radio-frequency module comprising:
- a packaging substrate configured to receive a plurality of components;
- and
- a multiplexer implemented relative to the packaging substrate, the multiplexer including a plurality of nodes and a common node, and a signal path implemented between each of the plurality of nodes and the common node, each corresponding signal path including a filter and a respective resonator, the plurality of corresponding signal paths configured to support carrier aggregation of respective signals through the common node.
A wireless device comprising:
- a receiver;
- a radio-frequency module in communication with the receiver, the radio-frequency module including a multiplexer having a plurality of nodes and a common node, the multiplexer further including a signal path implemented between each of the plurality of nodes and the common node, each corresponding signal path including a filter and a respective resonator, the plurality of corresponding signal paths configured to support carrier aggregation of respective signals through the common node;
- and
- an antenna in communication with the radio-frequency module, and configured to receive the respective signals.
