Description

The MA46600 series of microwave tuning varactors is a

family of abrupt junction gallium arsenide devices featur-

ing Q factors in excess of 8000. This series is specifically

designed for broadband high Q tuning performance (up

to 8000 at -4 volts and 50 MHz) from L through Ka band.

Characteristics such as high reliability, low leakage and

close capacitance tracking between diodes are typical of

these devices. Standard capacitance matching is ± 10%,

but closer matching is available upon request. All diode

types are available in a wide selection of ceramic pack-

ages as well as in chip form.

Applications

The MA46600 series of tuning varactors can be used for

both broad and narrow band tuning through Ka-band.

Typical applications include solid state tuning of VCOs

using transistors or Gunns as well as voltage tunable

filters and amplifier circuits. The GaAs abrupt junction

tuning varactors offer the highest Q of any tuning varac-

tors and are utilized in high frequency applications where

Q is premium.
