ELECTRONIC DEVICE AND METHOD INCLUDING POWER AMPLIFIER MODULE HAVING PROTECTION CIRCUIT - A simplified explanation of the abstract
This abstract first appeared for US patent application 17969302 titled 'ELECTRONIC DEVICE AND METHOD INCLUDING POWER AMPLIFIER MODULE HAVING PROTECTION CIRCUIT
Simplified Explanation
The abstract describes an electronic device that includes various components such as an antenna, a power amplifier module (PAM), a power management integrated circuit (PMIC), and at least one processor. The device is designed to amplify and transmit signals to an external electronic device.
- The device includes an antenna, PAM, PMIC, and processor.
- The PAM is responsible for amplifying the transmitting signal and has a protection circuit.
- The PMIC supplies voltage to the PA.
- The processor performs various functions related to signal transmission and protection.
- The processor provides signals to different gates in the protection circuit.
- The processor identifies whether to apply a bias voltage to the PA based on the signals.
- The transmitting signal is then transmitted to the external electronic device via the antenna.
