SILICON LOW VOLTAGE HYPERABRUPT VARACTOR DIODES
ZV950V2, ZV952V2, ZV953V2, ZMDC953, FSD273 Device Description
A range of silicon varactor diodes for use in frequency control and filtering. Featuring closely controlled CV characteristics, low voltage operation and high Q. Low reverse current ensures very low phase noise performance. These parts can be used with control voltages from 0.5V to 2.5V, making them ideal for 3 volt systems. Available in miniature surface mount packages.
Features
Close tolerance C-V characteristics Tuning from 0.5 to 2.5 Volts to suit 3 volt systems Low IR (typically 10pA) Excellent phase noise performance High Q at low voltage Miniature surface mount packages Band selection for DAB applications - FSD273
Applications
VCXO and TCXO Wireless communications Pagers Mobile radio Digital Radio receivers
