This paper presents the performance of tunable bandpass filters using high Q, wide-tuning-range passive tunable ICs. These passive tunable ICs are fabricated using ParaScan™, Paratek’s proprietary doped BST material. The tunable capacitors in these passive ICs have a tuning ratio of 4.15:1 and a Q factor over 100, from 100 MHz to 1 GHz. Two tunable filters using these passive tunable ICs were designed,...
Measurements of velocity microstructure in the upper water column on Georges Bank are used to contrast the summertime structure of turbulent kinetic energy dissipation rate between the central mixed area and the tidal-mixing front, and to compare vertical nitrate fluxes with frontal-zone primary production demands. In the mixed area during weak winds, the dissipation rate varies strongly over the...
