1.

All GaAs tuning varactors are available in chip form .

Please contact factory for part number information.

2.

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

along with case outlines in the appendix.

3.

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

ances are available upon request.

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 (Vbr) is measured at 10 microamps.

7.

The total capacitance and capacitance ratios shown are for

diodes housed in case style 30 with Cp= 0.170pF unless

otherwise specified. Other case styles will result in different

values.

8.

Part only offered in die form. The capacitance values are

for die form.

9.

Specification is for diode junction capacitance
