Description

The MA46600 series of microwave tuning varactors

is a family of abrupt junction gallium arsenide de-

vices 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 capaci-

tance 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 ce-

ramic packages 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 varactors and are utilized in

high frequency applications where Q is premium.
