Abstract: An optical fiber positioner having an elongated base with sidewalls and a longitudinally extending throughbore. A flexible optical fiber extends through the throughbore and has one end protruding outwardly from an end surface of the base. A plurality of actuators are secured to the sidewalls of the base so that an end of each actuator is positioned adjacent the end of the base. A crossbeam is then connected to the ends of each actuator so that the crossbeam moves laterally relative to the base in unison with the deflection of the actuators. The crossbeam has an opening through which the optical fiber extends so that the optical fiber deflects in unison with the lateral movement of the crossbeam. Various fixtures for assembly of the optical fiber positioner are also shown.

Abstract: An RF system comprising of outputs to an electronically scanning antenna for radiating electromagnetic energy; at least one waveform generator; two multiphase phase-locked loops integrated with the waveform generator, the phase locked loops operating to provide multiple shifted phases to a waveform. Optionally, the two multiphase phase-locked loops may each be divided down by a bank of frequency dividers to further increase the number of phase shifts. The phases generated from each multiphase phase-locked loops are selected with multiplexers then mixed together. These upper or lower sidebands are then mixed with the up converted waveform which results in a phase shift for the waveform associated with each antenna element.
