RADIO FREQUENCY FRONT END CIRCUITRY FOR CARRIER AGGREGATION

摘要

Radio frequency (RF) front end circuitry includes first RF multiplexer circuitry and second RF multiplexer circuitry. The first RF multiplexer circuitry is a quadplexer, while the second RF multiplexer is a triplexer. The RF front end circuitry is configured to support the transmission and reception of signals within a first operating band, a second operating band, and a third operating band. Further, the RF front end circuitry is configured to support carrier aggregation configurations between the first operating band and the third operating band and the second operating band and the third operating band.

1. Radio frequency (RF) front end circuitry comprising:
first radio frequency (RF) multiplexer circuitry coupled between a first common node and a first plurality of input/output nodes, wherein a filter response of the first RF multiplexer circuitry includes:
a first pass band configured to pass RF transmit signals within a first operating band between a first one of the first plurality of input/output nodes and the first common node;a second pass band configured to pass RF receive signals within the first operating band and RF receive signals within a second operating band between the first common node and a second one of the first plurality of input/output nodes;a third pass band configured to pass RF transmit signals within a third operating band between a third one of the first plurality of input/output nodes and the first common node;a fourth pass band configured to pass RF receive signals within the third operating band between the first common node and a fourth one of the first plurality of input/output nodes; andwherein the first RF multiplexer circuitry is configured to attenuate signals outside of the first pass band, the second pass band, the third pass band, and the fourth pass band; and second RF multiplexer circuitry coupled between a second common node and a second plurality of input/output nodes, wherein a filter response of the second RF multiplexer circuitry includes:
a fifth pass band configured to pass RF receive signals within the first operating band and RF receive signals within the second operating band between the second common node and a first one of the second plurality of input/output nodes; a sixth pass band configured to pass RF transmit signals within the second operating band between a second one of the second plurality of input/output nodes and the second common node;
a seventh pass band configured to pass RF receive signals within the third operating band between the second common node and a third one of the second plurality of input/output nodes; andwherein the second RF multiplexer circuitry is configured to attenuate signals outside of the fifth pass band, the sixth pass band, and the seventh pass band.
