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 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.
