Amplifier assembly with enhanced temperature compensated behavior, front end module, and mobile device including the same

A radio frequency module comprising:

• a packaging board configured to receive a plurality of components;
• an amplifier assembly implemented on the packaging board, the amplifier assembly comprising:
• an amplification circuit configured to amplify a radio frequency signal when biased by a biasing signal;
• a temperature sensing circuit configured to sense a temperature at a certain position of the amplification circuit;
• and at least one biasing circuit configured to generate the biasing signal with a temperature gradient dependent on the sensed temperature, the biasing circuit including a first transistor biased by a reference voltage and a second transistor biased by an input voltage proportional to the sensed temperature, the first transistor and the second transistor connected to a current source via respective slope resistors such to induce current proportional to the sensed temperature, the biasing circuit including a third transistor configured to output the biasing signal based on a control current flowing through the second transistor, the temperature gradient of the biasing signal being determined by the respective slope resistors.
