Design of Impedance Matching Networks for RF Applications
Keywords:Impedance matching, matching networks, RF, common-source amplifier, inductor, capacitor, s-parameters
This technical paper presents a design and study of impedance matching for RF (radio frequency) circuit application of common-source amplifier topology.Â Input and output matching networks of the amplifier were designed and computed ensuring unconditional stability.Â Inductors and capacitors are key passive components that are crucial for impedance matching, and are specifically designed such that they would satisfy the gain requirements at a specific frequency of operation.Â Impedance matching is necessary in RF circuit design to provide maximum possible power transfer between the source or the generator and the load.Â Complex tradeoffs among technology specifications and design parameters exist and should be carefully handled when designing the impedance matching networks, to optimize the performance of the amplifier.
