Abstract

The aim for this project is to design a 3.5GHz balanced mixer for WiMAX transceiver application. Mixers are used for frequency conversion and are critical components in modern Radio Frequency (RF) systems. A frequency mixer converts RF power at one frequency into power at another frequency to make signal processing easier and also inexpensive. Mixers rely on non linear relations between voltage and current to provide the multiple elements. Passive element that is used for the mixer circuit is BAT60A silicon schottky diode by Infineon. Datasheet can be view at Appendix A. Balanced mixers require hybrids, which will determine the bandwidth and overall performance of the mixer. Futhermore, single balanced mixer topology is choosed to make sure that the passive element produced the desired signal dan give simplicity to the design. The mixer circuit is design by using Advance Design System (ADS) software. This software is related with the circuit creation design which provide design tools and simulations. The design is built on FR4 board with specification of dielectric constant,
