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

Common Case styles
The MA46H070 through MA46H073 (gamma
0.75) family of constant gamma hyperabrupt GaAs
tuning varactors has quality factor approaching that of
abrupt junction varactors, but higher capacitance
change versus tuning voltage.These diodes are very
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-
