Description
The MA48700 series of Gallium Arsenide Abrupt Junction
Multiplier Varactors is specifically designed to provide
single state, high order multiplication at output frequencies extending to approximately 100 GHz. All varactors in
this series are available in either package or chip form.
The cathode is the heat sink end of the package.

Applications
This series of Gallium Arsenide Multiplier Varactors is
intended for medium power harmonic generation with
high conversion efficiency. These diodes may be used to
double or triple the frequency output of a phase locked
source for millimeter wave radar and communication systems for local oscillators and transmitters.

Electrical Characteristics
Notes:
1. Junction capacitance (Cj0) is measured at 1 MHz and 0 volts on a
bridge which has been balanced with a shielded test holder connected in place, but open circuited.
2. Cutoff frequency measurements (FC0) are made at 0 volts and
then extrapolated to -6 volts. See curve of Figure 1 showing typical
FC - 6 (cutoff at - 6 volts) versus FC0 (cutoff at 0 volts) performance curve.
3. Available in the case styles 30, 92, 94, 95, 120, 126, 128 and 166.
When ordering, specify the case style by adding the case style
number as a suffix to the basic part number.
4. Nominal package parasitics (Cp and Ls) are given for each case
style with the outline drawing in the appendix section.
