RF low-noise amplifier, oscillator and resistive mixer design

In the communication system, Low noise amplifier, oscillator and Mixer are the key components at the receiving and transmitting end. Due to high data rate requirement, many wireless applications at high frequencies have been proposed and developed. This master thesis deals with the designing of Single stage Low Noise Amplifier (LNA), Oscillator and Resistive mixer which operated at high frequencies by using same transistor. The circuit implementation and simulations are presented to verify the performance of Low noise amplifier, oscillator and mixer. At first, single stage low noise amplifier was designed to operate at 16 GHz using the Field Effect Transistor (FET), and then same transistor is used to build the fixed frequency oscillator operated at 16 GHz by using the techniques of unstabilization of a stable transistor. Finally a resistive mixer was designed using the same transistor, which operates as a down converter. There are several software packages in the industry that are used for the design and simulation of RF circuits. The one that we chose to use was Applied Wave Research's Microwave Office 2010. The primary reason for this choice was that we could obtain our own trial copy which gave us much more flexibility in the design process
