The invention provides a power supply control circuit, a relay control method and electronic equipment. The power supply control circuit comprises a power supply module and a relay module. The power supply module is configured to generate a control signal; the relay module comprises a relay, a first switch element and a bypass resistive element; a control end of the first switch element is connected with the power supply module and is used for receiving a control signal and switching a conduction state or a cut-off state according to the change of the control signal; the output end of the first switch element is connected with the relay and is used for controlling the closing or opening of the relay; the bypass resistive element is connected in parallel with the relay. The overall power consumption of the circuit can be remarkably reduced, and the circuit can adapt to the trend of miniaturized products.

The application discloses a 3D heterogeneous chip-based attenuator and an attenuation method thereof. The 3D heterogeneous chip-based attenuator comprises a first radio frequency chip and a second radio frequency chip. The first radio frequency chip is provided with a first radio frequency transmission line for transmitting a radio frequency signal, a first coupling member for coupling radio frequency signal energy and a second coupling member for coupling radio frequency signal energy. The first coupling member is electrically connected with an input end of the first radio frequency transmission line, and the second coupling member is electrically connected with an output end of the first radio frequency transmission line. The second radio frequency chip is provided with a second radio frequency transmission line for receiving the radio frequency signal on the first coupling member and outputting the radio frequency signal to the second coupling member. In the application, the first coupling member and the second coupling member can sequentially couple radio frequency signal energy to realize radio frequency signal energy attenuation, that is, the attenuator does not need to install a resistor on the first radio frequency chip when attenuating radio frequency signal energy, which improves the integration of the 3D heterogeneous chip.
