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 CAPACITANCE pF V R =0.5V, f=1MHz V R =1.5V, f=1MHz CAPACITANCE RATIO C 0.5 / C 2.5 f=1MHz Minimum Q V R =0.5V f=50MHz Min Min Max Min ZV950V2 9.5 6.3 7.8 2.0 ZV952V2 19 12.7 15.7 2.0 250 ZV953V2 45 30 37 2.0 200 ZMDC953(DUAL) 45 30 37 2.0 250 250 ZMDC953 is available banded to tighter capacitance range. This product has the order code FSD273TA. Measured at VR=1.5V the bands are Band A = 30.0 to 32.5 Band B = 32.3 to 34.7 Band C = 34.5 to 37.0 Product is supplied in reels. A banded reel will only contain a single band. Shipments containing several reels may have reels in different bands.
