    Abstract: A vector network analysis system and a method of measuring use offset stimulus signals to stimulate a balanced device under test (DUT) to determine performance parameters. The system includes an offset stimulus source that provides a plurality of stimulus signals and a vector network analyzer. At least one stimulus signal is offset from another stimulus signal of the plurality in one or both of frequency and time-varying phase. The offset stimulus source includes a first signal source and a second signal source that respectively provides the offset stimulus signals. The method of measuring includes generating the offset stimulus signals and applying the offset stimulus signals to a balanced port of the DUT to stimulate the DUT. The performance parameters are determined from measurements of the offset stimulus signals and one or more response signals from the stimulated DUT.

    Abstract: An impedance analyzer includes a reference signal, a first converter a first coupler, a second converter, a second coupler, a modification circuit, a reference signal detector, and a reflected signal detector. The first coupler couples the reference signal to the first converter. The first converter produces a reference intermediate frequency signal. The second coupler couples a reflected signal to the second converter. The second converter produces a reflected intermediate frequency signal. A reflection coefficient for a device under test is determined by using a reflected value detected by the reflected signal detector and a reference value detected by the reference signal detector. In a first operating mode of the impedance analyzer, the reflected intermediate frequency signal is forwarded directly to the reflected signal detector. In a second operating mode of the impedance analyzer, the modification circuit operates on the reference intermediate frequency signal to produce an adjustment signal that is combined with the reflected intermediate frequency signal before a resulting signal is forwarded to the reflected signal detector.

    Abstract: A low-pass filter transmission line with an integral electro-absorption modulator is described. In one aspect, the electro-absorption modulator functions as an element of a distributed low-pass filter transmission line circuit that is impedance-matched to a target source impedance. In this way, the electrical voltage that is delivered across the electro-absorption modulator may be optimized because the electrical losses do not occur in the low-pass filter transmission line circuit, but rather substantially all incident power is absorbed in a downstream matched termination load. In another aspect, the electro-absorption modulator has a signal electrode with a segmented traveling wave structure that provides substantially the same modulation performance as a similar un-segmented signal electrode of comparable effective length, but is characterized by a substantially higher bandwidth.

    Abstract: A tracking YIG tuned filter-mixer circuit is provided. In the preferred embodiment, four YIG-tuned resonators are combined to provide a tracking filter-mixer with a switched input. Field coils produce a magnetic tuning field that is uniform over the four YIG resonators. The first YIG resonator acts as the first stage of the filter, and in combination with a PIN diode circuit switches the RF input signal either to an output port or into the succeeding stages of the filter mixer. The second YIG resonator acts as the second stage of the filter. The third YIG resonator acts as the third stage of the filter, and as a fundamental mixer for combining the input RF signal with a swept LO signal to produce the IF output signal. The fourth YIG resonator acts as a discrimintor, comparing the LO frequency to the filter tuning frequency to generate an error signal for the field coil drive circuit. A small magnetic field coil over the fourth YIG resonator produces an offset magnetic field, tuning the fourth YIG resonator to the swept LO frequency, above the other three resonators by the IF frequency, so that the three YIG resonators that comprises the filter stages track the LO but are tuned to the RF frequency.
