Designing low pass filter for RF application / Mohammad Fairuz Ismail

This project focused on designing and building a low pass microstrip filter with a passband up to 3 GHz. The filter is intended to operate with other specifications: Equalripple Chebychev filter, passband ripple less than 0.5 dB and stopband attenuation at 6 GHz is more than 40 dB. This project was designed and simulated using CAD packages called Genesys and HP Eesof Libra. The microstrip laminates used was Duroid/Rogers 5872 with 0.5 mm substrate thickness and relative permittivity tjr equal to 2.33. The filter is then measured using a Wiltron Scalar Network Analyzer to obtain its precision.
