The phase equilibrium of the tensions obtained at the switch output (2) and, at the homologous terminals of the tested transformer 5, is compared with a phase discriminator 4 and a null indicator 6.
In another version, the device for identifying the clock-hour figure of the vector group for a three-phase transformer can be made by replacing the phase discriminator mentioned above, by a two-channel oscilloscope.
Reducing CW carrier leakage into the RF port of the mixers is critical to receiver performance since the resulting phase discriminator generates unwanted DC signal offsets.
Since the QIFM essentially is a phase discriminator, DQIFMs also can be used as phase discriminators when the LO and RF are located at the same frequency provided there is enough power at the LO port to bias the diodes.
Since the heart of the IFM is the phase discriminator, which, essentially, is a quadrature IF mixer (QIFM), the logical offshoot of the single-channel Micro DFD is a single-channel phase discriminator or QIFM.
Closing a phase-locked loop using the phase discriminator sets the two signal source carriers at precisely 90 [degrees], thereby satisfying both conditions.
Figure 3 shows an oscillogram of the phase discriminator output.
Key elements of indirect synthesizers are the VCO, the prescaler, which performs the frequency division, and the phase discriminator.
The phase shifters are suitable building-block components for aerospace and defense radar and EW applications involving phased-array antennas, phase discriminators, beamforming networks, and RF communication systems.
These building block components cover broadband microwave and millimeter wave frequencies and are ideal for aerospace and defense radar and EW applications which involve phased-array antennas, phase discriminators, beam forming networks and RF communication systems.
Comparators are op amps, ADCs are comparators, references have op amps, and PLLs use op amps as phase discriminators.
The company, world-renowned for microwave components, offers a wide selection of couplers, power splitters, combiners, mixers, PIN attenuators and phase discriminators in surface mount and connectorized forms.
