Design and development of band pass filter for X-band RADAR receiver system

This research paper mainly focuses on the study of X-band receiver and design and development of band pass filter for use in track RADAR project. A receiver block diagram was constructed; the received data is fed to the input of an Analogue-To-Digital Converter (ADC) that is limited by the ADC's maximum operating input power. Amplifiers, fixed attenuators pads, couplers, filters and mixers were chosen in order to implement a single-stage down conversion from a Radio Frequency (RF) of 9–10 GHz to an Intermediate Frequency of 1630MHz. To match the minimum gain of the receiver in enhancing the maximum power received within the range of the ADC, without saturating any components in the system a receiver is designed. Finally through this task a RADAR receiver design where the corresponding message has been encapsulated in the frequency band of 9GHz to 10GHz is being implemented.
