An electronically tunable filter at 1 GHz is presented. The filter uses a suspended substrate design and commercially available varactors for filter tuning. The filter has a 60% tuning range from 700 MHz to 1.33 GHz with a low insertion loss (better
Trends • More complex multilayer, multifunctional RF boards • Higher integration of different technologies like RF and Multichip Modules (MCM), die-in-board,... • 3D Stacking of board laminates with Multichip Modules and RF wireless technologies

An automatic visible spectrometer based on a non-collinear acousto-optic tunable filter (AOTF) is constructed for high-speed spectrometry. Its spectral filtering characteristics, such as relationships between the radio-frequency (RF) driving frequenc
Induced acoustic wave to bare fiber through various types of horn are examined. The center wavelength and extinction ratio of the notch filter are dynamically tunable and dependent on the RF signals.
