Abstract:
This dissertation aims towards the design analysis of 2.4/5.2 GHz dual band reflection type varactor based tunable phase shifter. Dual band impedence transforming 3 dB quadrature coupler is first designed at 2.4/5.2 GHz band in microstrip technology. Simulation and measured result is. presented for dual band impedence transformer.Then, dual band bias circuit is designed for 2.4/5.2 GHz. Dual band impedence transformer and dual band bias circuit is integrated with proper arrangement of varactors as reflection loads. EMDS Simulatin result of dual band phase shifter is presented at both bands.
