This paper presents a design of a multilayer bandpass filter. The filter is constructed from a combination of end-coupled and ring resonators for digital broadcasting applications. The filter is designed to work at 2.6 GHz with a bandwidth of 4%. A 0.75-mm-thick of Roger RO3003 substrate with dielectric constant, εr of 3.0 is used as a core material of the circuit. The bandpass filter was simulated...
This paper presents a 2.55-2.61 GHz bandpass filter using hairpin resonators in a multilayer configuration for digital broadcasting application. A combination of four-pole hairpin resonators was designed to operate at center frequency of 2.58 GHz with a bandwidth of 60 MHz. The best return and insertion losses in the passband are -23.753 dB and -2.4955 dB, respectively. The circuit was simulated using...
