PRESTO-HF: a toolbox dedicated to lowpass parameter identification for microwave filters http://www-sop.inria.fr/apics/Presto-HF . In order to allow the industrial transfer of our methods, a Matlab-based toolbox has been developed, dedicated to the problem of identification of low-pass microwave filter parameters. It allows one to run the following algorithmic steps, either individually or in a single shot:
-
determination of delay components caused by the access devices (automatic reference plane adjustment),
-
automatic determination of an analytic completion, bounded in modulus for each channel,
For the matrix-valued rational approximation step, Presto-HF relies on RARL2 (see Section 5.1 ). Constrained realizations are computed by the RGC software. As a toolbox, Presto-HF has a modular structure, which allows one for example to include some building blocks in an already existing software.
The delay compensation algorithm is based on the following assumption:
far off the passband, one can reasonably expect a good approximation of the
rational components of
This toolbox is currently used by Thales Alenia Space in Toulouse, Thales airborn systems and a license agreement has been recently negotiated with TAS-Espagna. XLIM (University of Limoges) is a heavy user of Presto-HF among the academic filtering community and some free license agreements are currently being considered with the microwave department of the University of Erlangen (Germany) and the Royal Military College (Kingston, Canada). A time-limited license has been bought by Flextronics for testing purposes.
