Abstract
Harmonic control apparatus of radio frequency (RF) devices are provided including an active device. In particular, the harmonic control apparatus includes a complementary open-loop resonator that is integrated in a conducting pattern of the harmonic control apparatus, to produce a shunt resonator that is configured to act as a short-circuit termination on at least one tuned frequency.
