Problems solved by technology

[0003] The design of the balun is related to the operating frequency of the communication device. In practical applications, different baluns are required for different frequency ranges. In the current design, the balun is difficult to replace, so multiple different baluns are set to deal with different frequencies. range, will cause the balun design area to be too large, which is not conducive to the miniaturization design of communication equipment

Embodiment Construction

[0029] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.

[0030] The type of balun is related to the operating frequency, that is, different baluns may be required according to different frequencies. If the balun structure is set in the circuit board of the front-end design, in the case of replacing the balun, multiple baluns with different structures can be set on the circuit board to apply to different frequencies, but this design will increase the circuit board. Design area; in addit...

Abstract

The invention provides an electronic device for a radio frequency front-end circuit and an electronic device. The electronic device comprises a substrate, a chip structure, a packaging structure, an impedance control structure and at least one balun structure, the chip structure is located on the substrate, wherein the at least one balun structure is located on the substrate and is in signal connection with the chip structure, each balun structure in the at least one balun structure comprises at least two resonators, the packaging structure covers the chip structure and the balun structures, and the impedance control structure is configured to adjust the effective length of the resonators so as to adjust the impedance ratio of the at least one balun structure. The electronic device is convenient to operate and high in reliability in practical application, amplitude and phase errors can be reduced, and maximization of the signal-to-noise ratio is achieved.

Description

technical field [0001] At least one embodiment of the present disclosure relates to the field of wireless communications, and in particular, to an electronic device and an electronic device for a radio frequency front-end circuit. Background technique [0002] In recent years, among communication devices with broadcast reception functions such as televisions and mobile phones, communication devices with two or more receiving systems have increased, and a distributor for distributing the input signal from the antenna into two is required; From the viewpoints of high frequency noise resistance of equipment and integration with ICs connected to distributors, balanced signals are generally used. Therefore, a balun that converts an unbalanced signal from an antenna into a balanced signal is required. [0003] The design of the balun is related to the working frequency of the communication equipment. In practical applications, different baluns are required for different frequency ...
