GaAs Abrupt Junction Tuning Varactors

MA46600 Series

Electrical Specifications at 25°C

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-

ing diode in a case style 30 with a C

Q at -4 volts and 50 MHz

≥7500. The capacitance values and capaci-

tance 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.
