MTV4090-X Datasheet, PDF (1/5 Pages) M/A-COM Technology Solutions, Inc. – Silicon Abrupt Tuning Varactor Diodes

MTV4090-x Series
Silicon Abrupt Tuning Varactor Diodes
Features
 Low Series Resistance
 High Q
 Extensive Selection of Capacitance Values
 RoHS* Compliant
Description
The MTV4090 Series tuning varactors are silicon
abrupt junction devices. They offer the highest Q
and lowest resistance available in 90 volt tuning
devices.
A unique silicon passivation process assures greater
stability, reliability, and low leakage currents at
higher temperatures.
The MTV4090 Series tuning varactors are used for
both narrow and wide band tuning through X-band.
These devices are used in circuits requiring a high Q
voltage variable capacitance such as tunable filters
and amplifiers, voltage controlled oscillators,
frequency synthesizers, and continuous phase
shifters. They are also useful as frequency and
phase modulators in communications applications.
