Inter-band uplink carrier aggregation radio frequency circuit, antenna device and electronic equipment

Abstract

The invention discloses an inter-band uplink carrier aggregation radio frequency circuit, an antenna device and electronic equipment. The inter-band uplink carrier aggregation radio frequency circuitcomprises a radio frequency transceiver, a primary antenna, a first secondary antenna, a first front-end radio frequency module and a second front-end radio frequency module; and the radio frequency transceiver is connected with the primary antenna by the first front-end radio frequency module and is also connected with the first secondary antenna by the second front-end radio frequency module, afirst frequency band uplink signal transmitted by the radio frequency transceiver is transmitted to the primary antenna by the first front-end radio frequency module, and a second frequency band uplink signal transmitted by the radio frequency transceiver is transmitted to the first secondary antenna by the second front-end radio frequency module so as to implement carrier aggregation of the firstfrequency band uplink signal and the second frequency band uplink signal. The uplink signals on the corresponding frequency bands are transmitted to the primary antenna and the secondary antenna by different front-end radio frequency modules so a to implement inter-band uplink carrier aggregation; and by isolation of the primary and secondary antennas, harmonic interference in the inter-band uplink carrier aggregation process is reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an inter-band uplink carrier aggregation radio frequency circuit, an antenna device and electronic equipment. Background technique [0002] With the development of communication technology, the current LTE, 5G and possible future communication technologies, in order to make full use of spectrum resources, the application of carrier aggregation is increasing. The main application of LTE carrier aggregation of mobile portable devices is DLCA (downlink Carrier aggregation) and intra-band contiguous ULCA (intra-band continuous uplink carrier aggregation), there are fewer applications for inter-band ULCA (inter-band uplink carrier aggregation). Because inter-band ULCA performs carrier aggregation between different frequency bands, the existing inter-band uplink carrier aggregation is usually implemented through the same quadplexer, but because of intermodulation, more h...

AI Technical Summary

Problems solved by technology

Inter-band ULCA performs carrier aggregation between different frequency bands. At present, the existing inter-band uplink carrier aggregation is usually implemented through the same quadplexer, but because of intermodulation, more harmonic interference is generated, which affects the performance of the product.
