TUNING VARACTOR
High Q silicon hyperabrupt junction tuning varactor
HIGH Q S ILICON HYP ERABRUP T J UNCTION TUNING VARACTOR
Description
This series of silicon tuning varactors consists of hyperabrupt epitaxial devices. They incorporate
a passivated m esa technology. Packaged or chip devices are available for linear electronic tuning from
VHF up to Ku band.
