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 order-
ing, specify the desired case by adding the case designa-
tion 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.
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.
6.
Breakdown voltage (VB) is specified at -10 μA.
