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 lo west leakage even at temperature extremes or dense SiO 2 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. APPLICATIONS/BENEFITS Wide bandwidth VCO.s Voltage Tunable Filters Phase Shifters Modulators VCXOs TCXOs
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.
