PRACTICAL IMPLEMENTATION AND TESTING OF A 3.6 MHZ BANDPASS FILTER

In this paper, a practical implementation and testing of a 3.6MHz Bandpass Filter (BPF) is presented. This circuit was design using butterwort filter design method and simulated using microwave office before the practical implementation and testing using real-world components and equipment. BPF is one of the arrays of components shaping the efficiency of communications systems that play a critical role in refining signal, mitigating interference, and enhancing the overall communication performance. Radio Frequency (RF) BPF has always been an indispensable part of RADAR and other wireless communication systems. The BPF have major functions of frequency band and channel selection, filtering harmonics, and suppress spurious. Therefore, RF BPF has always been a research hotspot in the field of wireless communication systems. The results indicated better performance of the at 3.6 MHz with -14.3 dBm and -13.3 dBm at 3.4MHz with excellent attenuation at cut-off frequencies or reject bands.
