The development of high-speed data access technology can’t be avoided <br /> <br /> <br /> <br /> <br /> accordingly with the needs and human demands which are never satisfied. This <br /> <br /> <br /> <br /> <br /> development also encourages the development of another technologies such as <br /> <br /> <br /> <br /> <br /> mixer technology which become the main research in the final project. <br /> <br /> <br /> <br /> <br /> The mixer technology developed due to high frequency information signal <br /> <br /> <br /> <br /> <br /> transmission will be translated into a low frequency signal to facilitate an easier <br /> <br /> <br /> <br /> <br /> processing. Due to this reason, mixer circuit that can perform up conversion or <br /> <br /> <br /> <br /> <br /> down conversion has become part of technologies that plays important role in the <br /> <br /> <br /> <br /> <br /> development of high-speed data access technology. <br /> <br /> <br /> <br /> <br /> Up converter will translate low frequency signals into high frequency signals <br /> <br /> <br /> <br /> <br /> before it is sent to antenna so it can be transmitted. In this project, up converter <br /> <br /> <br /> <br /> <br /> circuit is designed using IC LT5579 from Linear Technology. This IC is a double <br /> <br /> <br /> <br /> <br /> balanced mixer and this type possess advantages that appropriate with application <br /> <br /> <br /> <br /> <br /> requirements. <br /> <br /> <br /> <br /> <br /> Input and output ports of this IC were not in a matched condition for expected <br /> <br /> <br /> <br /> <br /> working frequency range. Therefore, additional matching impedance circuit will <br /> <br /> <br /> <br /> <br /> be needed to overcome this issue. The design will be based on the reference plant <br /> <br /> <br /> <br /> <br /> and will be analyzed using Smith Chart software and Ansoft Designer for circuit <br /> <br /> <br /> <br /> <br /> simulation. <br /> <br /> <br /> <br /> <br /> Up converter characterization will be a part of the project to determine circuit <br /> <br /> <br /> <br /> <br /> performance according to the determined parameters.
