Abstract:
1. An apparatus comprising: a first shunt arm comprising a first shunt path and a second shunt path, wherein (i) said first shunt path is connected in parallel with said second shunt path, (ii) said first shunt arm has a first impedance matching capacitance configured to operate at a fundamental frequency, (iii) said first shunt path comprises a first capacitor and a first inductor in series with a series resonance at a first harmonic frequency, and (iv) said second shunt path comprises a second capacitor and a second inductor in series with a series resonance at a second harmonic frequency; a series arm comprising a third inductor and a third capacitor, wherein (i) said third inductor is connected in parallel with said third capacitor, (ii) said series arm has a first impedance matching inductance configured to operate at said fundamental frequency; and a second shunt arm located between said series arm and an output port of said apparatus, wherein (i) said second shunt arm has a second impedance matching capacitance operating at said fundamental frequency, and (ii) said second shunt arm comprises a fourth capacitor and a fourth inductor in series with a series resonance.
