RF Basic Libraries#

The RF basic libraries provide parametric generators for common RF and microwave passive components. These pre-built functions automate the creation of complex geometries that would otherwise require manual calculation and drawing.

Summary#

These libraries enable rapid prototyping of RF circuits by providing:

  • Transmission Lines: Coplanar waveguide (CPW), differential pairs, and meandered lines

  • Passive Components: Spiral inductors, MIM capacitors, interdigital capacitors

  • Matching Networks: Radial stubs and other impedance transformation structures

  • Power Dividers: Rat-race couplers and other power splitting/combining circuits

  • Ground Structures: Hatched ground planes for controlled impedance
