SILICON DUAL VARIABLE CAPACITANCE DIODE
VBR=25V; IR=20nA; Cd=33pF(Nom)
The FSD270 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 33 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).
• 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
• DAB Receiver Modules for use with:
-Low voltage battery portables
-In car radio
• Voltage and Temperature Controlled Crystal Oscillators
• Mobile Radio and Pagers.
QUANTITY PER REEL
The FSD270 is capacitance selected into 3 bands. A reel will only contain one band - A,B or C. Shipments of more
than 1 reel may contain reels from different bands.
