ZMDC953TA

950 series 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 ISSUE 2 - MAY 2002 1 950 series TUNING CHARACTERISTICS at Tamb = 25 C PART CAPACITANCE pF V R =0.5V, f=1MHz Min ZV950V2 ZV952V2 ZV953V2 ZMDC953(DUAL) 9.5 19 45 45 CAPACITANCE pF V R =1.5V, f=1MHz Min 6.3 12.7 30 30 Max 7.8 15.7 37 37 CAPACITANCE RATIO C 0.5 / C 2.5 f=1MHz Min 2.0 2.0 2.0 2.0 250 250 200 250 Minimum Q V R =0.5V f=50MHz ZMDC953 is available banded to tighter capacitance range.
