:class:`RadialStub`
===================


.. py:class:: pyedb.libraries.rf_libraries.base_functions.RadialStub(edb_cell, radius: Union[str, float] = 0.0005, angle_deg: Union[str, float] = 60, width: Union[str, float] = 0.0002, layer: str = 'TOP', net: str = 'RF')

   
   Radial (fan) open stub for RF matching.


   :Parameters:

       **radius** : :class:`python:float`, :obj:`default` 500 µm
           Radius of the fan [m].

       **angle_deg** : :class:`python:float`, :obj:`default` 60°
           Opening angle of the sector.

       **width** : :class:`python:float`, :obj:`default` 0.2 :obj:`mm`
           Width of the feeding micro-strip line [m].

       **layer** : :class:`python:str`, :obj:`default` "TOP"
           Metal layer.

       **net** : :class:`python:str`, :obj:`default` "RF"
           Net name.











   .. rubric:: Examples

   >>> stub = RadialStub(radius=1e-3, angle_deg=90)
   >>> edb = Edb("radial.aedb")
   >>> stub._pedb = edb
   >>> stub.create()
   >>> f"{stub.electrical_length_deg(2e9):.1f}°"
   '108.0°'
