  • Temperature compensation circuit and radio frequency power amplifying circuit for radio frequency power amplifier
    Patent number: 10855231
    Abstract: A temperature compensation circuit for a radio frequency power amplifier includes: a temperature control circuit and a negative feedback circuit; the temperature control circuit is configured to generate a first electrical signal corresponding to a temperature, and according to the first electrical signal, adjust a second electrical signal at a first node; the negative feedback circuit is configured to provide, on the basis of the second electrical signal, a negative feedback signal to the radio frequency power amplifier by means of a second node; the second electrical signal is used to change the resistance value of the negative feedback circuit so as to adjust a negative feedback signal that is associated with the resistance value; the negative feedback signal is used to be inputted into the radio frequency power amplifier such that the gain of the radio frequency power amplifier changes.
