Abstract
This dissertation presents an approach of designing Ka Band Down Converter which are the combination of a Rat Race Mixer and Band-pass filter. Ka Band is the newest satellite broadcast band where Ka Band range is between 26.5 GHz to 40 GHz. The Ka Band Down Converter is designed to intend the operation at 38 GHz. The purpose of constructing the Ka Band Down Converter is to develop an application in wireless and radar systems. In order to develop the Ka Band Down Converter, the design construction is mainly focus on Rat Race mixer and Band-pass filter performances base on simulation perform using an Advanced Design System (ADS) from Agilent Technology. The simulation results showed the mixer and Band-pass filter design are able to operate at frequency 38 GHz for mixer and 233 MHz for filter. The Rogers RO4003C PCB type which is used in fabrication and the measurement reveal the hardware only able to perform up to 20 GHz only due to measurement equipment limitations.
