Free synthesis software for RF circuits: SynRF for Matlab
Our software SynRF allows you to perform the synthesis of RF circuits in seconds. SynRF calculates the element values and illustrates the transfer function over frequency. This gives you the information of the bandwidth of the circuits.
This software supports the calculation of:
- different attenuators,
- different impedance transformers from lumped and distributed elements,
- a lot of phase shifters,
- resistive and reactive power dividers,
- different couplers,
- actual only four (but in the next future much more) transmission lines,
- transmission line based inductors and capacistors,
- diverse mode blockers for even or odd mode reduction
- different baluns,
- lumped and distributed resonators,
- band pass filters with 1 to 3 resonators,
- a diplex filter.
The Heuermann HF-Technik GmbH introduced the first software for RF circuit synthesis. SynRF is based on the German text book from Prof. Heuermann Hochfrequenztechnik. Most of the included circuits were included in the software. Very novel circuits like the mode blocker are elements of the software.
The practical work with SynRF is shown in Fig. 2 for the bandpass filter with impedance transformation and a notch for the suppression of another band.
The actual SynRF version includes over 50 circuits.
