The MA46600 series of microwave tuning varactors
is a family of abrupt junction gallium arsenide devices
featuring 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
packages as well as in chip form.
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 varactors and are utilized in
high frequency applications where Q is premium.
