FRONT-END CIRCUITRY FOR MULTIBAND FREQUENCY MANAGEMENT

摘要

The described technology provides front-end antenna architecture for wireless communication that manages multiple frequency sub-bands in a manner that results is a low insertion loss rate. Further, the components of the architecture are smaller than typical wireless communication antenna architectures, and therefore the described architecture can be accommodated in a smaller area than typical architectures without a decrease in efficiency. A matching circuit is communicatively connected to each frequency sub-band's respective signal path. When two or more sub-bands are requested for high-speed wireless communication, the matching circuits match the impedance of each sub-band with one-another. Matching the impedance allows two or more sub-bands to be used to wirelessly communicate while maintaining high efficiency. The matching circuits are disabled when only one sub-band is needed for wireless communication.

主权项

1. A system for selectively connecting antenna signals of a wireless communication device, the system comprising:
switch bank circuitry configured to selectively communicate the antenna signals between at least one antenna port and at least one communication port, the antenna signals being allocated to one or more frequency bands, the one or more frequency bands being divided into one or more frequency sub-bands; and a frequency matched port assembly for each frequency sub-band communicatively connected to the switch bank circuitry and the communication port of the wireless communication device, the frequency matched port assembly including matching circuitry.
