skrf.circuit.Circuit.__init__¶
- Circuit.__init__(connections)[source]¶
Circuit constructor. Creates a circuit made of a set of N-ports networks.
- Parameters:
connections (list of list of tuples) – Description of circuit connections. Each connection is a described by a list of tuple. Each tuple contains (network, network_port_nb). Port number indexing starts from zero.
- Return type:
None
Examples
Example of connections between two 1-port networks:
connections = [ [(network1, 0), (network2, 0)], ]
Example of a connection between three 1-port networks connected to a single node:
connections = [ [(network1, 0), (network2, 0), (network3, 0)] ]
Example of a connection between two 1-port networks (port1 and port2) and two 2-ports networks (ntw1 and ntw2):
connections = [ [(port1, 0), (ntw1, 0)], [(ntw1, 1), (ntw2, 0)], [(ntw2, 1), (port2, 0)] ]
Example of a connection between three 1-port networks (port1, port2 and port3) and a 3-ports network (ntw):
connections = [ [(port1, 0), (ntw, 0)], [(port2, 0), (ntw, 1)], [(port3, 0), (ntw, 2)] ]
NB1: Creating 1-port network to be used as a port should be made with
Port()
NB2: The external ports indexing is defined by the order of appearance of the ports in the connections list. Thus, the first network identified as a port will be the 1st port of the resulting network (index 0), the second network identified as a port will be the second port (index 1), etc.
