Abstract
Methods are provided for embedding and/or de-embedding a network having an even number of ports into a device under test (DUT) having an odd number of ports. For example, a four-port network can be embedded/de-embedded into/from a three-port device under test (DUT). This is accomplished by embedding a virtual circulator into the three-port DUT to thereby generate an artificial four-port device. The four-port network is then embedded/de-embedded into/from the artificial four-port device to thereby generate a composite four-port device. The virtual circulator is then de-embedded from the composite four-port device to thereby generate a composite three-port device that is equivalent to the four-port network embedded/de-embedded into/from the three-port DUT.

A method for embedding a four-port network into a three-port device under test (DUT), the method comprising the steps of:
- (a) embedding a circulator into the three-port DUT to thereby generate an artificial four-port device;
- (b) embedding the four-port network into the artificial four-port device to thereby generate a composite four-port device;
- and
- (c) de-embedding the circulator from the composite four-port device to thereby generate a composite three-port device that is equivalent to the four-port network embedded into the three-port DUT.
A method for embedding a network into a device under test (DUT) having an odd number of ports, the method comprising the steps of:
- (a) embedding a circulator into the DUT to thereby generate an artificial device having an even number of ports;
- (b) embedding the network into the artificial device to thereby generate a composite device;
- and
- (c) de-embedding the circulator from the composite device to thereby generate a further composite device that is equivalent to the network embedded into the DUT.
A method for de-embedding a four-port network from a three-port device under test (DUT), the method comprising the steps of:

- (b) de-embedding the four-port network from the artificial four-port device to thereby generate a composite four-port device;
- and
- (c) de-embedding the circulator from the composite four-port device to thereby generate a composite three-port device that is equivalent to the four-port network de-embedded from the three-port DUT.
