Description

The

MAVR-000400

series

are

ion-implanted,

hyperabrupt junction, silicon tuning varactors in the

SOT-23 surface mount package. These thermal

oxide passivated diodes feature high capacitance

ratio and quality factor. They are well suited for

octave bandwidth tuning in the HF to UHF frequency

bands. The standard capacitance tolerance is

±10%, with tighter tolerances available. Capacitance

matching at one or more bias voltages is also

available. These diodes are supplied with 100%

matte Sn plating.

Applications

The MAVR-000400 series tuning varactors are

useful for octave bandwidth tuning applications in

the HF through UHF ranges. Applications include

VCOs and voltage tuned filters in radios, cable TV

tuners and test instruments where low cost and

excellent lot-to-lot repeatability are critical. Linear

tuning performance is available from 3 to 8 volts.
