1. Describe

The non-ideal characteristics of a true capacitor can be ignored at low frequency. Physical size imparts capacitor inductance and Electrodes and metal electrodes contribute to resistive losses, but the effect of these electrodes on the circuit is usually negligible. These effects become important at the very high frequencies of radio communications (>100MHz) and satellite systems (>1GHz). Recognizing that a true capacitor will exhibit inductive and resistive impedances in addition to capacitance, the ideal capacitor for these high frequencies is an ultra-low loss component that can be fully characterized in all parameters and can vary from one unit to Another unit with full repeatability. Until recently, most high frequency/microwave capacitors were based on Firing ceramic (porcelain) technology. Layers of ceramic dielectric material and metal alloy electrode paste are interleaved and then sintered in a high temperature oven. The technique exhibits component variability in dielectric quality (loss, permittivity, and insulation resistance), variability in electrode conductivity, and variability in physical dimensions (affecting inductance). An alternative thin-film technology has been developed that virtually eliminates these differences. It is this technology that has been fully integrated into Accu-P® and Accu-P® to provide high frequency capacitors with truly desirable characteristics.
