TUNING VARACTOR
Plastic package, Surface Mount hyperabrupt tuning varactor
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...
