LumpedElementFilter

rfnetwork.elements.LumpedElementFilter

class rfnetwork.elements.LumpedElementFilter(shunt=False, passive=False, state={})

Bases: Network

Parameters

shuntbool, default: False: If True, port 2 is connected to ground and port 1 is transformed into a 2-port component that can be cascaded with other components.
passivebool, default: True: if True, evaluate calls evaluate_sdata instead of evaluate_data and noise correlation matrix is computed passively.
statedict, optional: dictionary of state variables specific to each component. Keys must be component designators. The state values can be read with the state property and changed later with set_state(). Attempting to set the state of variables that were not included in the initial dictionary will raise an error.

Examples

>>> import rfnetwork as rfn

>>> class Wilkinson(rfn.Network):
...    
...     upper = rfn.elements.Line(z0=70.7, length=0.4)
...     lower = rfn.elements.Line(z0=70.7, length=0.4)
... 
...     r1 = rfn.elements.Resistor(100)
... 
...     nodes = [
...         ("P1", upper|1, lower|1), # port 1 node
...         (upper|2, r1|1, "P2"),  # port 2 node
...         (lower|2, r1|2, "P3")  # port 3 noode
...     ]

>>> w = Wilkinson()

Methods

`LumpedElementFilter.from_butterworth`(fc, ...)	Parameters fc1 float Lower 3 dB cutoff frequency [Hz] fc2 float Upper 3 db cutoff frequency [Hz] n int Filter order (1-10). Odd n will be matched to 50 ohms, while even n requires an impedance match.
`LumpedElementFilter.from_chebyshev`(fc, btype, n)	Parameters fc1 float Lower 3 dB cutoff frequency [Hz] fc2 float Upper 3 db cutoff frequency [Hz] n int Filter order (1-10). Odd n will be matched to 50 ohms, while even n requires an impedance match. ripple float, default: 0.5 Passband ripple in dB
