Rancang Bangun Radio Frequency Amplifier 9,3 Ghz Untuk Coastal Radar

ABSTRACT This research designs and builds an RF amplifier with a frequency of 9.3 GHz for use in portable coastal radars which are used as a tool to monitor sea areas. This research designs and builds an RF amplifier that works at a frequency of 9.3 GHz using a stub matching technique as an impedance matcher. In this design, the RT/Duroid 5880 substrate is used with a dielectric constant of 2.…
