PLASTIC PACKAGE, SURFACE MOUNT HYPERABRUPT
TUNING VARACTOR
Description
This series of silicon tuning varactors consists of hyperabrupt epitaxial devices. They incorporate
a passivated mesa technology. This family is designed for a low cost medium to high volume market that
may be supplied in tape and reel for automated pick and place assembly on surface mount 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 moderate frequency bandwidth applications (VCO mainly)
from HF to Microwave frequencies (up to 3 GHz). Other applications are voltage tuned filters, phase
shifters, delay lines...
