Abstract: In this dissertation, a concurrent dual-frequency oscillator with a concurrent dual-band matching network has been proposed. This report primarily focuses on the analysis and design of concurrent dual-band oscillator using Advanced Design System (ADS) with Electromagnetic Design Simulator (EMDS). The oscillator generates, concurrently, two signals of frequencies 2.44G1-lz and 5.25GHz. Concurrency of the oscillator has advantage that it provides multiple functionalities, high transmission data rate and system reliability. Firstly, the concurrent dual-frequency HEMT based oscillator have been designed using two transistors, two separate resonators for 2.44G1-Iz and 5.25GHz and a common dual-band matching network is discussed. It can be used for the Wireless LAN applications. The matching network is designed by using micro strip lines. Finally, the concurrent dual-frequency oscillator using single transistor have been designed. Here dual-band matching network and dual-band biasing network with radial stub has been used, radial stub have the advantage of large bandwidth, low reflection loss. Dual-frequency oscillator using single transistor has the advantage of low cost, low power dissipation. The dissertation provides an in-depth analysis of schematics, EMDS simulation and fabrication of proposed concurrent dual-frequency oscillator.
