1. A radio frequency (RF) amplifier device comprising:
an input stage configured to receive an RF input signal;
an amplification stage configured to generate an amplified RF signal based at least in part on the RF input signal, wherein the amplification stage has a first frequency-dependent profile; and
a transformer comprising:
a first winding configured to receive the amplified RF signal;
a second winding providing 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, wherein a resonance frequency of the resonator is tuned to provide a second frequency-dependent profile for the transformer, and wherein the second frequency-dependent profile compensates for the first frequency-dependent profile.
