Marki Microwave offers a variety of models to support system development using our components.
For passive, linear devices (such as power dividers, filters, diplexers, couplers, bias tees,
equalizers, and baluns) linear S-parameters fully characterize the performance of the device and
are most suitable for all simulation platforms. Marki offers S-parameters files for all passive,
linear devices as well as amplifiers at a variety of bias conditions. These are available on an
individual product basis in the table above, or on the individual product page. These
S-parameter based models are also available in Systemvue for download below, and the complete
set is also available. Nonlinear and noise models for amplifiers and limiters are currently in
development.
Frequency converting devices such as mixers, multipliers, IQ mixers, and comb generators are
best characterized with fully nonlinear models, available below for ADS and Microwave Office.
Marki Microwave is proud to publicly offer our non-linear simulation design kits for both
Cadence® AWR® Microwave Office® (MWO) and Keysight’s PathWave Advanced Design System
(ADS). At Marki Microwave we strive to offer top tier engineering support with experts in all aspects
of the RF & Microwave field. The best-in-class RF & Microwave components demand engineering support
that is up to par. In keeping with this philosophy, both MWO and ADS design kits offer simulation
models for our Microlithic and MMIC mixer and multiplier products. Support for both design kits
is ongoing and verified through measurement. If you do not see the part you are interested in simulating,
try looking for it as a bare die with the ‘-CH’ suffix. We do not offer models including packaging
effects so bare die performance will be closest to performance of the packaged mixer.
You won’t find mixer S-parameters on our website. For non-linear devices S-parameters are
not meaningful. S-parameters only shows small-signal behavior and don’t allow for large-signal analysis. X-parameters,
the superset of S-parameters, do allow for large-signal analysis; however, X-parameter models are
both environmentally dependent and depend on the device under test’s input condition. Both of these
behavioral models do a good job for passive linear components like power dividers and couplers,
and you’ll find downloadable S-parameters on our website for all of our passive components.
Heavily non-linear devices such as mixers, doublers, and NLTLs demand physics-based models
capable of accurately simulating non-linear effects of the diodes within the circuits. This
is precisely what our design kits do.Numerical solutions through harmonic balance simulations are the time efficient way of
performing non-linear analysis such as IP3 and spurious output prediction early in the design
cycle. Days and weeks of careful characterization can be reduced to a few hours with the
design and debug support offered by our simulation design kits. For an overview of the design
kits, examples of its accuracy, and a complete list of products supported please see our Brief Guide to Marki Mixer Simulation Models.
Keysight PathWave System Design (SystemVue) offers advanced prototyping and design platform for
complex RF systems based on measurement data for components. Marki currently offers a complete
library of linear S-parameters within PathWave System Design software. Nonlinear models are not
currently supported, but are in development.
