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 (C

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 avail-

able upon request. By adding the suffix A to the part number, a toler-

ance 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 (V

7. The total capacitance and capacitance ratios shown are for diodes

housed in case style 30. Other case styles will result in different val-

ues.
