Tuning Varactors
Tuning Varactors:
MTV 4030 Series
30-Volt Abrupt Tuning Varactors
Description
The
MicroMetrics
MTV 4030 series
Tuning Varactors are silicon abrupt
junction devices. They offer the
highest Q and lowest resistance
available in 30 volt tuning diodes.
A unique silicon dioxide passivation
process assures greater stability,
reliability and low leakage currents
at higher temperatures.
Applications
The MTV 4030 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.
Standard capacitance tolerance is
±10%. Diodes can be optimized for
custom electrical or mechanical
specifications upon request.
Features
• Low Series Resistance - High Q
• Extensive Selection of Capacitance
