LC Ladder block

To add a block to a model, double-click the canvas and start typing the block name. Then, select the block from the list.

Libraries:
RF Blockset / Circuit Envelope / Elements

Description

The LC Ladder block models common two-port LC lossless networks. To learn how you can use LC Ladder to compare the input and output signal amplitudes to study the signal attenuation, see Model RF Filter Using Circuit Envelope.

Parameters

Ladder topology — Type of ladder topology

LC Lowpass Tee (default)

Type of ladder topology, specified as one of the following:

Ladder Topology

LC Lowpass Tee
LC Lowpass Pi
LC Highpass Tee
LC Highpass Pi
LC Bandpass Tee
LC Bandpass Pi
LC Bandstop Tee
LC Bandstop Pi

Inductance — inductance values

[1.3324e-5 1.3324e-5] H (default) | real number

Inductance value, specified as a real number in Henries. Specify the units of the inductance from the corresponding drop-down menu.

Data Types: double

Capacitance — Capacitance value

1.1327e-9 F (default) | real number

Capacitance value, specified as a real number in Farads. Specify the units of the capacitance from the corresponding drop-down menu.

Ground and hide negative terminals — Internally ground and hide the negative terminals

on (default) | off

Select this option to internally ground and hide the negative terminals. Clear this to expose the negative terminals. By exposing these terminals, you can connect them to other parts of your model.

Programmatic Use: Add Block

To add the block programmatically, use the add_block function with one of these library block paths as the source.

"simrfV2elements/LC Ladder"

Example: add_block("simrfV2elements/LC Ladder","myModel/myBlock",MakeNameUnique="on")
