This is a special SPICE model library for those users performing simulations at or above 200MegHz. It contains custom designed subcircuit models for 600+ different RF devices including bipolar transistors, PIN diodes, FETS, MMICs, and RF beads.
The RF library allows any SPICE program to simulate high frequency circuits using linear and nonlinear AC, DC, and Transient analyses. A capability not available before because of the lack of quality subcircuit based models. If your RF models are only using the standard Gummel-Poon BJT model then you need this library. All models are characterized up to their published s-parameter data.
