Abstract

In this paper, a bandpass filter with cutoff frequencies 1.7-11.5GHz have been implemented. For construction of this filter, the first design two filters lowpass and highpass with cutoff frequencies 1.7 GHz and 11.5GHz respectively and then they use in series. We design cutoff frequencies independently, consequently, designing cutoff frequencies doesn’t interfere with each other. The end, filter is fabricated on the Ro4003 dielectric substrate with thickness of 32mil and Er=3.38. The simulated and measured results agree well with each other.
