The Focus Compact Model (FCM) utility is a streamlined software package designed to be used with Focus’ AURIGA high-end pulse system, that is used to generate Compact Models for transistors from their Pulsed-IV and wideband pulsed s-parameter data.
This is achieved by generating a network of lumped circuit elements that represent accurately the fundamental linear & non-linear behaviour of the device over a broad range of bias and power range.
The result of the modelling is a netlist and compatible with- the most common CAD tools used in RF Design such as AWR Microwave office (MWO) and Keysight Advanced Design Studio (ADS).
Key features of the FCM:
- Linear and Non-Linear Compact Transistor Model Extraction of III-V materials (GaN HEMT or similar model).
- High frequency FET model parameters from a combination of DC and S-parameter measurements.
- Gate-lag and drain-lag trapping.
- Basic thermal model extraction.
8 Extrinsic parameters (RG, RD, RS, LG, LD, LS, CPG, CPD )
