mount gallium arsenide tuning varactors. All families
have silicon nitride protected junctions for low
leakage current and high reliability.
The
MA46H070
through
MA46H073
family has
hyperabrupt junctions with constant gamma of 0.75
from 0 to 20 volts and very high quality factor
approaching that of abrupt junction varactors, but
higher capacitance change versus tuning voltage.
These diodes are very well suited for narrow
bandwidth VCOs and VTFs where wide tuning range
and very high quality factor are required.
The
MA46H200
through
MA46H204
family has
hyperabrupt junctions with constant gamma of 1.25
from 2 to 20 volts and has the largest capacitance
ratio of the families of GaAs varactors and high
quality factor. These diodes are very well suited for
wide bandwidth VCOs and VTFs where the optimum
combination of very wide tuning range and high
quality factor is required.
The
MA46H500
through
MA46H504
family has
hyperabrupt junctions with constant gamma of 1.5
from 2 to 12 volts and high quality factor. Designed
for wide bandwidth VCOs and VTFs where limited
bias voltage is available. These varactors have
lower quality factor than the other families of GaAs
varactors.

3. 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).
4. The Cp values listed typically have tolerances of ±0.02 pF.
5. Capacitance is measured at 1 MHz.
6. The total capacitance and capacitance ratios shown are for diodes housed in case style 30. Other case styles will result in different values.
7. When ordering MA46H202-134 as whole wafer P/N is MAVR-0046202-0134WR.

Ordering Information
These GaAs tuning varactors are available in either case style as shown. When ordering, specify the desired case
style by adding the case designation as a suffix to the model number. For example, a MA46H200-1088 specifies
a 1.25 gamma hyperabrupt tuning diode in case style 1088.
