Description
The MA46600 series of microwave tuning varactors is
afamily 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
Notes:
1. Capacitance is measured at 1 MHz on a bridge which has been
balanced 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
tuning diode in a case style 30 with a CT14 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.
3. All junctions are abrupt i.e., y = 0.50 ± .03.
4. 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.
5. Case parasitics (Cp and Ls) are given for most case styles.
