All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
To better understand the solution of the embodiments of the present application, the following is first introduced:
in the 4G era, the cost and the architecture design are limited, and the uplink path has only 1 power amplifier, so that the electronic device has only 1 transmitting antenna at the same time, and the upper antenna or the lower antenna can be selected to transmit signals according to the network condition, which is the switching of the upper antenna and the lower antenna of the 4G, and the quality of the transmitted signals of the electronic device is improved under different use conditions (i.e., different hand-holding conditions) of the handheld electronic device. With the development of communication technology and the arrival of the 5G era, the networking mode of 5G is divided into independent networking (Stand Alone, SA) and Non-independent Networking (NSA). Currently, most operators lay base stations of NSA, which requires the existence of 4G and 5G at the same time, so that two sets of 4G and 5G uplink PAs are needed in the architecture.
Specifically, as shown in fig. 1b, the 4G still maintains the original path, and for a New Radio Frequency Division Duplexing (NR FDD) Frequency band signal of 5G, the New NR FDD Frequency band signal is output by the Radio Frequency transceiver, amplified by the 5G PA, transmitted by the transmitting module, the DPDT switch, and the multiplexed 4G transmitting antenna, and transmitted on the antenna 1 or the antenna 2.
Present electronic equipment seeks the full-face screen for electronic equipment's antenna headroom district is more and more littleer, and to the low frequency, the direct influence antenna performance that the headroom reduces, to the operator, more hopes that the low frequency has good antenna performance, because the frequency channel of low frequency is low, and the wavelength is long, is the important frequency channel that improves signal coverage, and low frequency performance worsens, can direct influence user's signal quality, and the low frequency goes upward signal is good, can have better network coverage.
