Description Applications
M/A-COM offers four families of low cost surface
mount gallium arsenide tuning varactors. All fami-
lies have silicon nitride protected junctions for low
leakage current and high reliability.
The
MA46H500 through MA46H504
family has
hyperabrupt junctions with constant gamma of 1.5
from 2 to 12 volts and high quality factor.
The
MA46H200 through MA46H206
family has hy-
perabrupt junctions with constant gamma of 1.25
from 2 to 20 volts and higher quality factor.
The
MA46H070 through MA46H073
family has
hyperabrupt junctions with constant gamma of 0.75
from 0 to20 volts and very high quality factor.
The
MA46504 through MA46506
family has abrupt
junctions with constant gamma of 0.5 from 0 to 30
volts and the highest quality factor.

Applications
The
MA46H500 through MA46H504 (gamma 1.5)
family of constant gamma hyperabrupt GaAs tuning
varactors is designed for wide bandwidth VCOs and
voltage tuned filters where limited bias voltage is
available. These varactors have lower quality fac-
tor than the other families of GaAs varactors.
The
MA46H200 through M46H206 (gamma 1.25)
family of constant gamma hyperabrupt GaAs tuning
varactors has the largest capacitance ratio of the
families of GaAs varactors and high quality factor.
These diodes are very well suited for wide band-
width VCOs and VTFs where the optimum combi-
nation of very wide tuning range and high quality

The

0.75)
family of constant gamma hyperabrupt GaAs
tuning varactors has quality factor approaching that of
abrupt junction varactors, but higher capacitance

well suited for narrowerbandwidth VCOs and VTFs
where wide tuning range and very high quality factor
are required.
The
MA46504 through MA46506 (gamma 0.5)
family ofconstant gamma abrupt GaAs tuning varac-
tors has the highest quality factor. These diodes are
very well suited for narrower bandwidth VCOs and
VTFs where highestquality factor is of paramount con-

1. Case parasitics (Cp and Ls) are given for most case styles along with case outlines in the appendix. The Cp values listed typically have tolerances of ±0.02 pF.
2. 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).
3. Capacitance is measured at 1 MHz.
4. Reverse voltage (VB) is measured at 10 microamps.
5. The total capacitance and capacitance ratios shown are for diodes housed in case style 30. Other case styles will result in different values.

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.
