Abstract Details

2011, Master of Science, Ohio State University, Electrical and Computer Engineering.
This thesis presents two tunable matching network designs relying on varactors. The matching network should provide and instantaneous optimized impedance according to different power levels of the power amplifier. The matching networks are designed for an high efficiency class B power amplifier operating at 2 G Hz. Two topologies for the load matching network are considered in this thesis: the Pi network and the T network. The varactors are integrated as part of the load network. By changing the biasing voltages on the varactors, the value of capacitors can be varied and the output impedance modified. The design procedure followed consists in determining the design parameters yielding the maximum load impedance range that can be provided by the network. The major research steps followed include (1) the computational algorithm development, (2) ADS simulations, (3) circuit fabrication and (4) measurements.
