rfckt.lchighpasstee class

Package: rfckt

Highpass tee filter

Syntax

h = rfckt.lchighpasstee
h = rfckt.lchighpasstee('Property1',value1,'Property2',value2,...)

Description

Use the lchighpasstee class to represent a highpass tee filter as a network of inductors and capacitors.

The LC highpass tee network object is a 2-port network as shown in the following circuit diagram.

In the diagram, [L1, L2, L3, ...] is the value of the 'L' object property, and [C1, C2, C3, ...] is the value of the 'C' object property.

h = rfckt.lchighpasstee returns an LC highpass tee network object whose properties all have their default values.

h = rfckt.lchighpasstee('Property1',value1,'Property2',value2,...) returns an LC highpass tee network object, h, based on the specified properties. Properties that you do not specify retain their default values.
