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.

Notes:
1. Capacitance is measured at 1 MHz on a bridge which has been bal-
anced with shielded test holders connected in place but open circuited.
2. All GaAs tuning varactors are available in any case style shown in this
bulletin as well as in chip form. When ordering, specify the desired
case by adding the case designation as a suffix to the model number,
i.e., MA46601-30. For example, a MA46601-30 specifies a 30 volt tun-
