SOT23 SURFACE MOUNT SILICON ABRUPT

TUNING VARACTOR

Description

This series of silicon tuning varactors have an epitaxial mesa design with a high temperature

passivation. This technology is used to produce abrupt tuning varactor in SOT23 package. 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.

Applications

The DH71000 series abrupt tuning varactor are offered in a large selection of capacitance range.

They provide the highest Q factor (low reverse series resistance) available for a 30 volts silicon device.

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 line, etc.

NOTE: Variation of the junction capacitance versus reverse voltage follows this equation:
