# LN Card

This card defines a complex load to any non-radiating network port that is not connected to geometry (that is any non-radiating network of the type Internal).

On the Source/Load tab, in the Loads / networks group, click the  Load icon. From the ドロップダウンリスト, click the  Load network (LN) icon.

## Parameters:

Define a load at a network port
Define a network load with the following parameters.
Remove all LN type loads previously defined
All previously defined LN type loads are removed. This replaces all network loads with open circuits. Note that setting the load impedance to zero creates a short circuit between the network terminals.
Network name
The network or transmission line name, with the network port number, that uniquely identifies the connection terminals.
Network port number
The network port number, with the network or transmission line name, that uniquely identifies the connection terminals.
Complex impedance
Define the real and imaginary parts of the complex impedance in Ohm using Real part of impedance (Ohm) and Imaginary part of impedance (Ohm) respectively.
Series circuit
The resistor value in Ohm, inductor value in Henry and the capacitor value in Farad to be added as a series circuit.
Parallel circuit
The resistor value in Ohm, inductor value in Henry and the capacitor value in Farad to be added as a parallel circuit.
SPICE circuit
Specify the name of a one-port SPICE circuit to define a load between two pins. Define the SPICE circuit using the SC card.
Touchstone file
Specify a one-port Touchstone file (.s1p, .z1p, .y1p) to define a load.
Note: If the load is added to a port that has a voltage source, the load is placed in series with the voltage source.
Real part of impedance (Ohm)
The real part of the complex impedance in $\Omega$ .
Imaginary part of impedance (Ohm)
The imaginary part of the complex impedance in $\Omega$ .
