| Summary: | This research thesis describes the detailed methodology on the design of the 136-
941 mhz wideband low noise amplifier (lna) for software defined radio (sdr) base
station in two-way radio applications. The operating frequencies of the design are based
on the full spectrum (wideband requirement) of the tia-603c standard for land mobile
fm communication equipment. The lna design process includes a comprehensive
circuit analysis, design methodology and performance comparisons of the two wideband
topologies selected for this research, the negative feedback technique and balanced
amplifier topology. This research thesis also illustrates the simultaneous amplifier
requirements in wideband application and proposed a structured practical design
approach which utilizes the cad simulations in optimizing the amplifiers to meet all the
required specs, to balance the design tradeoff and the drawing of the pcb layouts. The
design process also includes the method of achieving accurate correlation between the
simulation and the actual design. The final stage of the research process was the
fabrication of the two topologies using rogers r04003c pcb board and the practical
testing measurement of the design using rf equipment to verify the performance of the
designed lna. |
