SILICON DUAL VARIABLE CAPACITANCE DIODE
SUMMARY
VBR=25V; IR=20nA; Cd=47pF(Nom)
DESCRIPTION
The ZDC834A is a new hyperabrupt SOT23 packaged dual common cathode
varactor diode , offering users both compact circuit design and impressive
performance comprising tightly controlled CV characteristics, a capacitance
of typically 47 pf @ 2V,excellent phase noise performance and high Q of 200
min.
This superior performance in the VHF and UHF ranges has been optimised to
meet the high filtering requirements of a wide range of Digital Audio
Broadcasting (DAB) module circuits , mobile radios, pagers, voltage
controlled crystal oscillators (VCXO) and temperature controlled crystal
oscillators (TCXO).
FEATURES
• Common Cathode dual Diode ( monolithic construction )
• VHF- UHF operation
• Close tolerance CV characteristics
• High Tuning Ratio
• Low IR , enabling excellent Phase Noise Performance
( IR typically < 200pA @ 20V )
• High Q
APPLICATIONS
• DAB Receiver Modules for use with:
- Low voltage battery portables
- Hi-Fi
- In car radio
- MP3 players
• Voltage and Temperature Controlled Crystal Oscillators
• Mobile Radio and Pagers.
