UHF-MICROWAVE SUPER HYPERABRUPT JUNCTION
VARACTOR DIODES
DESCRIPTION
The KV 1900 series of super hyperabrupt varactor diodes combines low voltage with high ratio tuning. They
feature grown junction mesa technology for the highest
Q commercially available. Passivation is our dense mil
spec silicon dioxide for the lowest 1/F noise and low
leakage even at temperature extremes. They are available in a wide range of package styles including chip
(style 00) and most other conventional ceramic microwave packages. When ordering, specify the desired
case style by adding its number as a suffix to the basic
model number. For more details on surface mount Super
Hyperabrupt Varactors see the Surface Mount Devices
section.
