Embodiment 1

[0152] This example takes dual antennas as an example. The workflow for the high-frequency band is as follows: the high-frequency signal is output from the main transceiver and enters the high-frequency power amplifier for amplification; the amplified high-frequency signal is connected to the high-frequency antenna switch through the high-frequency antenna switch. High-frequency coupler, high-frequency antenna switch realizes the connection between the hardware channel of different high-frequency bands and the high-frequency coupler; the high-frequency signal transmitted to the high-frequency coupler is divided into two channels, and the main signal is output through the high-frequency coupler To the high-frequency antenna, the high-frequency coupling signal is output from the coupling port of the high-frequency coupler, and transmitted to the main transceiver through the power feedback switch; the detector inside the main transceiver detects the high-frequency feedback signal, ...

Description

technical field [0001] The invention relates to signal processing technology, in particular to a multi-antenna radio frequency circuit and a radio frequency signal processing method. Background technique [0002] With the development of Long Term Evolution (LTE, Long Term Evolution) technology, wireless terminals are required to support a wider communication bandwidth, which poses a greater challenge to antenna design. Currently, wireless terminals are limited by requirements such as cost and size, and a single antenna cannot further effectively widen the antenna bandwidth. For this reason, multi-antenna technology is gradually introduced in wireless terminal design to solve the problem of insufficient bandwidth coverage of a single antenna. [0003] The emergence of multiple antennas puts forward new requirements for the radio frequency circuit of the wireless terminal. The current multiple antennas have only one transceiver, and the circuit of multiple antennas and multip...
