RF Designer - Components (Stripline Elements)

Postby rftools » Thu Aug 18, 2016 4:44 am

All components found in the stripline catalog require a substrate to be defined in RF Designers Substrate Manager. This can be found under Settings->Substrates on the Action Bar menu. If a substrate for a component is not selected when simulating the circuit, RF Designer will choose the first substrate defined in the Substrate Manager for the simulation. If no substrate has been defined, the simulation will stop and an error dialog will appear.

SLIN - Stripline Transmission Line

Image




NameDescriptionUnitsDefault Value
WWidthDimension20 mil
LLengthDimension1000 mil
SUBSubstrateFirst substrate in list


Model for a stripline transmission line with width W and length L. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.

SCLIN - Symmetric Coupled Striplines

Image





NameDescriptionUnitsDefault Value
WWidthDimension25 mil
SGapDimension10 mil
LLengthDimension1000 mil
SUBSubstrateFirst substrate in list


Model for a pair of symmetric edge coupled stripline transmission lines. Width W defines the trace width for both striplines whose length is define by L. The coupled lines are seperated by a gap distance of S. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.

SLOC - Open Circuit Stripline

Image




NameDescriptionUnitsDefault Value
WWidthDimension20 mil
LLengthDimension100 mil
SUBSubstrateFirst substrate in list


Model for a length of open-circuited stripline transmission line with width W and length L. This model does not take into account the loss or capacitance at the open end of the line. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.

SLSC - Short Circuit Stripline

Image




NameDescriptionUnitsDefault Value
WWidthDimension20 mil
LLengthDimension100 mil
SUBSubstrateFirst substrate in list


Model for a length of short-circuited stripline transmission line with width W and length L. This model does not take into account the loss or inductance at the shorted end of the line. It is assumed that the line terminates into a perfect electrical conductor that is a ground reference. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.

SLEF - Open Circuit Stripline with End Effect

Image




NameDescriptionUnitsDefault Value
WWidthDimension20 mil
LLengthDimension100 mil
SUBSubstrateFirst substrate in list


Model for a length of open-circuited stripline transmission line with width W and length L including the open end effect. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.

SSTEP - Stripline Step in Width

Image




NameDescriptionUnitsDefault Value
W1Node 1 WidthDimension50 mil
W2Node 2 WidthDimension20 mil
SUBSubstrateFirst substrate in list


Model for an abrupt step in the width of a stripline transmission line. For best results, nodes 1 and 2 should be connected to stripline elements with the same widths defined by W1 and W2. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.

SGAP - Gap in Stripline

Image




NameDescriptionUnitsDefault Value
WWidthDimension20 mil
SGap LengthDimension5 mil
SUBSubstrateFirst substrate in list


Model for a series gap in a stripline transmission line. The width of the stripline is defined by W and is the same for both sides of the gap. The length of the gap is defined by S. For best results, both ends of the SGAP component should be connected to a stripline component whose width matches the defined width W. This model requires a substrate to be defined in the Substrate Manager which can be found under Setting->Substrates.
