What does DC stand for?

Other topics include slot and hollow waveguides, directional couplers, ring resonators, silicon modulators, diffraction gratings, silicon-on-insulator waveguides, Bragg gratings, and multi-quantum-well solar cells.

Microwave test accessories include adapters and connectors, amplifiers, fixed attenuators, variable attenuators, DC Blocks, power limiters, power dividers, power splitters, cable Assemblies, calibration kits, detectors, directional couplers & bridges, terminations, loads, test port cables, waveguide accessories, and RF and microwave switches.

The Model 102020010 Directional Coupler features a frequency range of 2-20 GHz.

The final end product of the contract will be to economically produce high bandwidth, small chip, stable, low voltage, low loss, ultra linear polymer directional coupler modulators.

After introducing the nomenclature and notations, seven chapters discuss integrated optics, including coverage of step-index thin-film waveguides, graded-index thin-film waveguides, propagation loss in thin-film waveguides, three-dimensional waveguides with rectangular boundaries, optical directional couplers and their applications, guided-wave gratings, and arrayed-waveguide gratings.

The splitter or equal-loss power divider is used at branch junctions where equal-length trunk branches are required; the directional coupler or unequal-loss power divider is used at branch junctions where unequal-length trunk branches are required.

In addition, a directional coupler is integrated into the modules thus eliminating the need for any external coupler.

The Company's portfolio includes amplifiers, attenuators, detectors, diodes, directional couplers, front-end modules, hybrids, infrastructure RF subsystems, mixers/demodulators, phase shifters, PLLs/synthesizers/VCOs, power dividers/combiners, receivers, switches and technical ceramics.
