3.1.1 circulator
three-port device in which the incident wave to any port is transmitted to the next port according to an order of sequence determined by the sense of a static magnetic biasing field
Note 1 to entry:By reversing the magnetic biasing field, the order of sequence is reversed.
Note 2 to entry:This property may be used to switch electromagnetic waves.[SOURCE: IEC 60050-726:1982，726-17-08, modified - The word“multiport" is replaced by "three-port"]
3.1.2 isolator
two-port device having much greater attenuation in one direction of propagation than in the opposite direction[SOURCE: IEC 60050-726:1982, 726-17-19]
3.2 RF characteristics parameters
3.2.1 insertion loss
Lins
resulting from the insertion of a network into a transmission system, the ratio of the power delivered to that part of the system following the network, before insertion of the network, to the power delivered to that same part after insertion of the network Note 1 to entry: The insertion loss is generally expressed in decibels.[SOURCE: IEC 60050-726:1982, 726-06-07]
4.1 ldentification and types
General description of the function of the RF MEMS circulator/isolator and their applications should be stated. The statement should include the details of manufacturing technologies about the RF MEMS circulator/isolator with different operation, configuration, and actuation mechanism. The statement should also include packaged form including terminal numbering and package materials.
The RF MEMS circulator/isolator shall be clearly and durably marked in the order given below:
a) manufacture's name or trade mark;
b) device type and serial number;
c) year and week (or month) of manufacture;
d) terminal identification (optional);
e) factory identification code (optional).
4.2 Application and specification description
Information on application of the RF MEMS circulator/isolator shall be given. Block diagrams of the RF MEMS circulator/isolator and the applied systems should be also given. AII terminals should be identified in the block diagram and their functions shall also be stated.BS IEC 62047-41 pdf download.
