The embodiment of the invention provides a conversion circuit, a conversion method, a radio frequency chip, a radio frequency transceiver and electronic equipment, relates to the technical field of radio frequency, and is used for solving the problem of how to meet the requirements of a radio frequency chip port on a signal type and a power range. A first adjustable attenuator, a first phase shifter and a second adjustable attenuator; the first adjustable attenuator is coupled with the first differential terminal, and the second adjustable attenuator is coupled with the single-end port; the first phase shifter is coupled between the first adjustable attenuator and the second adjustable attenuator; the first phase shifter is used for performing phase shift on the received signal by-90 degrees; a third adjustable attenuator, a second phase shifter and a fourth adjustable attenuator; the third adjustable attenuator is coupled with the second differential terminal, the fourth adjustable attenuator is coupled with the single-end port, and the second phase shifter is coupled between the third adjustable attenuator and the fourth adjustable attenuator; and the second phase shifter is used for performing 90-degree phase shift on the received signal.
