C. LUMPED ELEMENTS
A total of 27 different types of lumped elements and com-
binations of lumped elements are available for network topology.
In all cases, resistances are given in ohms, capacitances in
picofarads, and inductances in nanohenries. Angles for CCS and
VCS sources are always positive. A table describing each of
these elements can be found on pages 6 through 12.
D. FILE ELEMENTS
Four types of file elements are provided. The names of
the files for these elements are limited to 8 characters. The
files referred to have been written by the user by use of the
data file editor or as a result of having saved the response
S-parameters of a previous problem. Use of the data file edi-
tor is covered in the following chapter. For the description
of these element types, refer to the table on page 14.
E. DISTRIBUTED ELEMENTS
Elements consisting of sections of transmission line are
common throughout high frequency design, and are provided in
order to give the user the maximum amount of flexibility in
circuit design. Transmission line, open and shorted stubs,
and one case of coupled lines are available. Refer to the
table on page 13 for full details.
F. INTERCONNECTIONS AND TRANSFORMATIONS
Five interconnections and 4 transformations are available
for arranging elements to form a network. The usage of these
commands is covered in the following section on creating net-
works. See pages 15 to 17 for descriptions of these commands.
G. CREATING NETWORKS
Creating a network is a matter of defining the topology
of the circuit to be analyzed. With schematic in hand, one
simply defines the circuit in terms of elements; lumped, dis-
tributed, or file. These are then interconnected using the
