  • Vector Network Analyzer-Noise Figure Measurement
    Publication number: 20080238441
    Abstract: A noise receiver is included in a network analyzer block diagram such that noise power and S-parameters measurements can be made almost simultaneously without mechanical switching in the test set. Additionally, a variable mismatch device tuner that is used by the network analyzer for S-parameter calibrations, is further used during the noise figure measurements method to remove the effect of source match variations so that the expected noise figure performance of the DUT when connected to a desired input (probably 50 ohms) can be determined.

  • Integrated directional bridge
    Patent number: 7309994
    Abstract: A directional bridge for measuring propagated signals to and from a source device to a load device where both the source device and load device are in signal communication with the directional bridge is disclosed. The directional bridge may include a first bridge circuit network and a first sensing element in signal communication with the first bridge circuit network. The first sensing element may produce a first measured signal that is proportional to the propagated signals.
