UHF Microwave Super-Hyperabrupt Junction
TM
RoHS Compliant
DESCRIPTION
The KV1900 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
tough MIL-Spec ceramic glass for lowest leakage even at temperature
extremes or dense SiO₂ for lowest 1/F noise. 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 KV19x1A Super
Hyperabrupt Varactors in popular high performance surface mount
packages, see the KV19x2A & KV19x3A series products.
KEY FEATURES
 Available as packaged devices or
as chips for hybrid applications
 Typical 4:1 Tuning Range
 Ultrahigh Q
 Values for frequencies from UHF
through X band.
APPLICATIONS
The KV19x1A series is an ideal choice for low voltage battery supplied
VCOs covering frequency ranges from UHF through 12 GHz. They are
used widely in analog phase shifters and phase modulators in microwave
communications. They are also excellent choices for higher overtone, high
pull VCXO and TCXO applications.
