Abstract

The invention provides a communication device and an electronic device. Wherein, the communication device includes: an antenna, a frequency division circuit and at least one variable impedance circuit. Wherein, the frequency division circuit has a common port, the common port is coupled to the antenna and at least one output port, and the frequency division circuit is used to divide the frequency range received from the common port into multiple frequency sub-ranges and divide the multiple frequency sub-ranges into At least one of the frequency sub-ranges is respectively output to the at least one output port; and each of the at least one variable impedance circuit is coupled to a corresponding output port and a first output port of the at least one output port of the frequency division circuit. A reference voltage, and each variable impedance circuit respectively provides a variable impedance value switched between different impedance values. The communication device provided by the invention can effectively suppress harmonic interference in the communication device.

Description

technical field [0001] The present invention relates to communication devices, and more particularly, to communication devices that can support communication in multiple frequency sub-ranges or carrier aggregation domains. Background technique [0002] To meet Long Term Evolution-Advanced (LTE-A) requirements, it is necessary to support a transmission bandwidth wider than 20 MHz specified in 3GPP Release 8 / 9. For this, the preferred solution is carrier aggregation, which is one of the most prominent features of 4G LTE-A. Carrier aggregation allows extending the effective bandwidth of transmissions to user terminals through the parallel use of radio resources across multiple carriers. Multiple component carriers are aggregated to form a larger overall transmission bandwidth. [0003] However, the technique of carrier aggregation requires multiple frequency bands or sub-ranges and a wide frequency bandwidth. Designing such antenna systems to meet the demands of carrier aggr...
