Hyperabrupt Junction Tuning Varactor

SMV1270-079

Features

■ High Capacitance Ratio

■ Ultra Small Size SC-79 Package

■ Designed for High Volume, Low Cost

Battery Applications

■ Available in Tape and Reel Packaging

Description

The SMV1270-079 is a silicon hyperabrupt junction varactor

diode specifically designed for battery operation.The

specified high capacitance ratio and low R of this varactor

Absolute Maximum Ratings

make it appropriate for low noise VCOs used at frequencies

in wireless systems to beyond 2.5 GHz. Applications include

low noise and wideband UHF and VHF VCO for GSM, PCS,

CDMA and analog phones.
