Strong command of the following technical disciplines: Matching and filters: Impedance, Smith charts, series and shunt matching, lumped and distributed networks, transmission lines, reflections, VSWR, and tradeoffs among Q, network complexity, loss, and bandwidth. Receivers: Noise figure and cascaded noise analysis, SNR, noise power and density, decibel quantities, gain distribution, front-end and pre-detector filtering, nonlinear effects, IIP3, frequency conversion, images, mixing spurs, and phase noise.
