I want to design a harmonic resonator that will become open circuit for a certain frequency(even harmonic) and short circuit at a certain frequency (odd harmonic).
From my design simulation, at the operating freq (2GHz), Zin=50ohm. at second harmonic freq ( 4GHz), Zin = 8ohm and at third harmonic freq (6GHz) Zin=10k ohm.
again at 4th harmonic (8GHz), Zin = 9ohm and 5th harmonic (10GHz), Zin = 8k ohm.
my question is, Can I consider Zin = 8ohm and 9ohm as short circuit and also Zin= 10k ohm and 8k ohm as open circuit?
