Abstract:
This paper gives the simple comparison of bandpass filter and presents the design of Butterworth filter for a wideband wireless receiver. The bandpass filter was designed for covering the major wireless application frequency ranges from 0.4 GHz to 5GHz. The band pass filter was designed to have impedance matching at the input port and output ports. The results achieved shows good input matching at input port (S11) and good output matching at output port (S22) with return loss characteristics of above -300 dB. The transmission characteristics S21 gives the effective bandwidth achieved for the design which covers the entire broad pass band with an effective bandwidth of 4.6 GHz. The design of Band pass Filter has been developed in the planar form as strip lines using the design parameters with the simulation software Ansoft designer 4.1.
