UHF-MICROWAVE SUPER HYPERABRUPT JUNCTION
VARACTOR DIODES
DESCRIPTION
The KV 1900 series of super hyperabrupt varactor di-
odes 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 avail-
able in a wide range of package styles including chip
(style 00) and most other conventional ceramic micro-
wave 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.
