Theory
- Transmission Line - Part
of a Masters thesis by Joachim Johansson
and Urban Lundgren. Starts out with
derivations of the general transmission
line equations, followed by the
time-harmonic equations. This is followed
by derivation of basic transmission line
formulas, such as for characteristic
impedance, capacitance, and propagation
constant.
PCB
Impedance Calculator - By
SunMan Engineering. Calculates either the
characteristic impedance, or one of many
other parameters for a given
characteristic impedance, for a PCB
microstrip, embedded microstrip
(off-center stripline), stripline, or
dual stripline. Also calculates
capacitance and propagation delay per
unit length.
Microstrip
Trace Impedance Calculator -
Calculates either impedance, copper
width/weight, or dielectric thickness.
Also calculates capacitance, inductance,
and propagation delay.
Embedded
Microstrip Trace Impedance Calculator -
Where there is dielectric material both
above and below the copper strip.
Calculates either impedance, copper
width, or copper weight. Also calculates
capacitance, inductance, and propagation
delay.
PCB
Trace Impedance Calculator -
Includes calculators and formulas for
microstrip, embedded microstrip,
stripline, and dual stripline traces. (By
the UMR EMC Laboratory.)
Theory
- Transmission Line - Part
of a Masters thesis by Joachim Johansson
and Urban Lundgren. Starts out with a
general model diagram for unbalanced
lines. Then describes how to model
balanced lines.
Artech
- TRANSLIN: Transmission Line Analysis
and Design -
Design and analysis of coaxial,
microstrip, coplanar, and coupled lines,
as well as waveguides. Requires Windows
3.1 or higher. (Sold only through online
book/software retailers.)
Applied
Wave Research - TX-Line - Free
Windows-based transmission line
calculator. Eagleware
- T/Line -
Transmission line synthesis. Kirkby
- ATLC -
Freeware (GNU license) by Dr. David
Kirkby (G8WRB). ATLC stands for Arbitrary
Transmission Line Calculator. Consists of
several Unix programs that calculate
transmission line characteristics for
various geometries (coaxial cable,
microstrip, etc.) including arbitrary
shapes. Can also be used for designing
couplers. Requires compiling with gcc
(also freeware) or other C compiler. FNC
- Elcad -
General purpose schematic-designer and
parts-calculator. For designing antennas,
LC matching networks, tuned circuits, air
and toroidal-core coils, and active
filters. Does transmission line
calculations, antenna scaling, and all
basic electronics calculations. WAØJOW

Stripline
Impedance Calculator -
Calculates either impedance, copper

Also calculates capacitance, inductance,
and propagation delay.
Asymmetric
Stripline Impedance Calculator -
Where the strip is off-center within the
dielectric material. Calculates either
impedance, copper width/weight, or
dielectric offset. Also calculates
capacitance, inductance, and propagation
delay.

Theory
- Transmission Line - Part
of a Masters thesis by Joachim Johansson
and Urban Lundgren. Complete yet concise.
Includes mathematical derivations of the
basic transmission line equations.
Includes diagrams of three common types
of baluns.
About
Balun -
Includes a little theory behind baluns,
and how to build them. Covers the choke
balun, Collins balun, transmission line
balun, bazooka balun, and VHF balun.
4:1
Coax Balun Design -
Using a 1/2 Lambda coax balun. Includes
an online calculator.
Animated
Standing Wave Calculator -
Visualizing what a standing wave looks
like is always difficult. Type in any
reflection coefficient, VSWR, mismatch
loss, or return loss and this Java applet
will not only convert among the values,
but it will also present an animation of
the incident, reflected, transmitted, and
standing waves.
