The Worldwide Interoperability for Microwave Access, or WiMax, is a wireless communication technique based on IEEE 802.16 standards. Its advantage of sending high data rates over long distances, while using a single base station to cover a large area, has made this technique a flexible and reliable solution for public wireless networks. WiMax has two main types of networks: Fixed and Mobile.
The most popular transceiver used in WiMax applications is the “Direct-Conversion
Architecture” due to its high level of integration and less component requirements,
which leads to reduced power dissipation.
In Direct Conversion Architecture, the mixer is a key block in the transceiver chain. Depending on design specifications and constraints, different types of mixers may be considered.
However, the most appropriate down converter mixer for WiMax applications is the Gilbert-cell mixer. This thesis will then explore the design of a down converter Gilbert-Cell Mixer within the realm of Fixed WiMax technology. This design was achieved in the commercial circuit simulator Advanced Design System (ADS) using the 0.15mm InGaAs pHEMT technology process provided by Win Semiconductor Crop.
