First Claim
Patent Images
1. A harmonic control apparatus of a radio frequency device comprising an active device including at least one input terminal and an output terminal, the harmonic control apparatus comprising:
- a conducting pattern in a first conducting layer, being disposed on a first side of a planar dielectric substrate, facing a second conducting layer on an opposite side of the planar dielectric substrate, the second conducting layer acting as a ground plane; and
a complementary open-loop resonator integrated in the conducting pattern to produce a shunt resonator that is configured to act as a short-circuit termination on at least one tuned frequency,wherein the conducting pattern is formed on a semiconductor substrate on which the active device is integrated;
wherein the complementary open-loop resonator comprises two concentric rings, the resonator being modeled by an equivalent electric circuit comprising two series transmission lines, a resistance, an inductance and a capacitance that are configured to determine at least one tuned harmonic frequency; and
wherein the concentric rings are physically connected to each other.
