ABSTRACT:
An asymmetrical coupling circuit for use in a network analyzer is provided with a pair of couplers coupled to the input and output ports of a device under test (DUT) for improving the dynamic range of forward and reverse transmission measurements. The through-arms of the couplers are used to connect the input and output ports of the DUT to the reference signal source and measuring circuit to thereby eliminate the attenuation caused by feeding a signal through the coupling arm of the coupler as occurs in symmetrical coupler arrangements.
