Abstract
The embodiment of the application provides an electrical field, and particularly relates to a radio frequency front-end circuit and electronic equipment. The radio frequency front-end circuit comprises a power divider, a first PA, a second PA, a phase compensation unit, a 90-degree phase conversion unit and a 180-degree phase conversion unit. The first port of the power divider and the junction point are sequentially connected in series with the phase compensation unit, the first PA and the 90-degree phase conversion unit. The second port of the power divider and the junction point are sequentially connected in series with the second PA and the 180-degree phase conversion unit. The radio frequency front-end circuit has a wide working bandwidth, and the circuit occupies a small area.
