1. A radio frequency (RF) amplifier device comprising:
one or more RF components configured to generate an amplified RF signal based at least in part on an RF input signal, wherein the one or more RF components have a first frequency-dependent profile; and
a transformer comprising:
a first winding configured to receive the amplified RF signal;
a second winding configured to provide an RF output signal based at least in part on the amplified RF signal; and
a resonator comprising:
a third winding at least partially coupled to the first winding and the second winding; and
a circuit network configured to tune a resonance frequency of the resonator to provide a second frequency-dependent profile for the transformer, wherein the second frequency-dependent profile compensates for the first frequency-dependent profile.
