Tschebysheff parallel-coupled BPF for K-band application

Abstract

This paper described the design, simulation and fabrication of a parallel-coupled band pass filter. The design was for K-band applications with bandwidth of 300 MHz. The filter was operated between 21 to 21.3 GHz. The circuit was designed and simulated using Genesys and the measurement was carried out after fabrication on RT Duroid 5870 with 0.508 mm thickess and the dielectric constant, epsivr of 2.33 and dielectric loss tangent of 0.001. The results shows a good agreement between simulation and measurement.
