1.

All GaAs tuning varactors are available in chip form as well

as the case styles shown on the following page. When

ordering, specify the desired case by adding the case des-

ignation as a suffix to the type number.

2.

Case parasitics (Cp and Ls) are given for most case styles

along with case outlines in the appendix. The Cp values

listed typically have tolerances of ±0.02 pF.

3.

The nominal tolerance at -4 Volts is ± 10%. Closer toler-

ances are available upon request. By adding the suffix A to

the part number, a tolerance of ± 5% at -4 Volts is guaran-

teed.

4.

The values guaranteed for gamma are measured on un-

packaged chips. The total capacitance versus bias voltage

curve will deviate slightly from the chip capacitance versus

bias voltage curve due to the package parasitic capaci-

tance (Cp).

5.

Capacitance is measured at 1 MHz.

6.

Reverse voltage (VB) is measured at 10 microamps.

7.

The total capacitance and capacitance ratios shown are for

diodes housed in case style 30. Other case styles will re-

sult in different values.
