In this study, an application of a Chebyshev Bandpass Filter designed in Richards Space for the sub-6GHz band of 5G communication is presented. In the first stage, the theoretical design was accomplished using the Simplified Real Frequency Technique (SRFT). As a result of the theoretical design, a filter covering the N77, N78, and N79 communication bands (3.3- 5GHz) was obtained by combining 7 commensurate transmission lines. The filter exhibits 0.01dB Insertion Loss Ripple (ILR) in the passband and 35dB Insertion Loss (IL) in the stopband. In the subsequent stage, the filter elements were converted to microstrip transmission lines and Rogers RO4725JXR was selected as the substrate material. Simulations were performed using Keysight ADS software. Based on the EM analysis results, circuit elements were optimized to minimize discontinuity effects and approach ideal behaviors. In the final stage, the produced filter was measured using the Rohde & Schwarz ZVB14 Network Analyzer, reaching loss values of –2.892dB and –1.196dB for frequencies of 3.3GHz and 5GHz, respectively.
