Motorola's Impedance Matching Program is a specialized form of CAD specifically developed for RF power amplifier circuit design. It provides a simple environment for entering and analyzing impedance matching circuitry regularly employed in RF Power amplifier design.
Data sheets for RF devices contain large signal impedances (measured at a single combination of frequency, voltage, power level and power dissipation). These impedances must generally be transformed to another set of impedances (50 W or the input/output impedance of another device). To do this, MIMP provides a standard library of passive circuit elements; including various combinations of capacitors, inductors and transmission lines in both series and shunt configurations. It also contains a unique, DISTRIBUTED CAPACITANCE ELEMENT that models a capacitor distributed along a transmission line.
