TUNING VARACTOR DIODES

Sprague-Goodman silicon based varactor diodes offer a broad selection of models for operation from VHF through Microwave frequencies.

Control of the epitaxial junction growth process in the construction of our varactor diodes, produces several desirable characteristics, such as highly linear tuning, high Capacitance tuning ratios (Ct/Vr), and superior Q values.

Sprague-Goodman varactor diodes are available with a variety of responses of Capacitance versus Voltage (C-V curves), described as abruptness of the junction. Package styles include the plastic surface mount SOT-23 package, and higher performance ceramic substrate packages for more demanding surface mount applications.
