P LASTIC PACKAGE, S URFACE MOUNT HYP ERABRUP T  
TUNING VARACTOR  
Description  
This series of silicon tuning varactors consists of hyperabrupt epitaxial devices. They incorporate  
a passivated m esa technology.This fam ily is designed for a low cost m edium to high volum e m arket that  
m ay be supplied in tape and reel for autom ated pick and place assem bly on surface m ount circuit boards.  
Application  
The DH76000 and DH77000 series hyperabrupt tuning varactor are offered in a large selection of  
capacitance range. They provide the highest Q factor (low reverse series resistance). Typical  
applications include low noise narrow and m oderate frequency bandwidth applications (VCO m ainly)  
from HF to Microwave frequencies (up to 3 GHz). Other applications are voltage tuned filters, phase  
shifters, delay lines...
