Notes:
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 designation 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 toler-
ances of ± 0.02 pF.
3. The nominal tolerance at -4 Volts is ± 10%. Closer tolerances are
available upon request. By adding the suffix A to the part number, a
tolerance of ± 5% at -4 Volts is guaranteed.
4. The values guaranteed for gamma are measured on unpackaged
chips. The total capacitance versus bias voltage curve will deviate
slightly from the chip capacitance versus bias voltage curve due to the
package parasitic capacitance (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
