Description
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.

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.

Typical Performance Curves
Capacitance is measured at 1 MHz on a bridge which has
been balanced with shielded test holders connected in
place but open circuited.
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 tuning diode in
a case style 30 with a Ct@-4v between .36 and .44 pF and
a Q at -4 volts and 50 MHz 7500. The capacitance values
and capacitance ratios are for case style 30. Other case
styles or chips will have slightly different values.
All junctions are abrupt i.e., y = 0.50 ± .03.
Total capacitance ratios will vary with case choice due to
differences in case capacitance (Cp). Figure 1 shows the
ratio for the 30 case style.
Case parasitics (Cp and Ls) are given for most case styles.
Breakdown voltage (VB) is specified at -10 μA.
