ABSTRACT:
A method for measuring a frequency translation device under test by using a vector network analyzer and a reference frequency translation device that includes measuring the network characteristics of the reference frequency translation device by using the vector network analyzer, measuring the network characteristics of a circuit including the reference frequency translation device and the frequency translation device under test by using the vector network where the reference frequency translation device has an operation complementary to the frequency translation device under test, and removing the network characteristics of the reference frequency translation device from the measured network characteristics of the circuit.
