Abstract :
A new band-pass filter (BPF) implemented by a dielectric monoblock and its design techniques are presented. The modeling of the three-pole BPF using a single dielectric block has been carried out by CAD. The equivalent circuit of the BPF was established by transmission lines and lumped capacitors. The transmission line characteristic impedances were computed using 2-D FEM. The BPF for PCS has been designed to have a 60 MHz pass-bandwidth with center frequency of 1960 MHz and an attenuation pole at below the passband using a commercial 3-D structure simulator
