# Discrete Loads

Load a wire port, microstrip port, FEM line port, general networks and a transmission line with a discrete load such as a complex impedance, series circuit or parallel circuit.

## Complex Impedance

A frequency-independent load consisting of a constant real and imaginary part. This load type can be applied to wire, edge, network or transmission-line ports.

## Series Circuit

A frequency-dependent load consisting of a series-connected resistor (R), capacitor (C) and inductor (L). This load can only be applied to a wire port and an edge port. The load impedance is given by

## Parallel Circuit

A frequency-dependent load consisting of a resistor (R), a capacitor (C) and inductor (L) connected in parallel. This load can only be applied to a wire port and an edge port. The load impedance is given by

**inside the circuit**, but the circuit itself is connected

**in series**with the source.
