Abstract
A power amplification circuit may comprise a power distributor configured to receive a radio frequency (RF) signal and output a first RF signal and a second RF signal, a first power amplifier configured to receive the first RF signal from the power distributor and amplify the first RF signal based on a first bias, a second power amplifier configured to receive the second RF signal from the power distributor and amplify the second RF signal based on a second bias, an impedance matching circuit configured to receive the first RF signal amplified by the first power amplifier and the second RF signal amplified by the second power amplifier, and a protection circuit configured to identify a current input to a bias terminal of the second power amplifier and, control a magnitude of the current input to the bias terminal based on the identified input current.
