Description
M/A-COM offers four families of low cost surface mount
gallium arsenide tuning varactors. All families have sili-
con nitride protected junctions for low leakage current
and high reliability.
1088
The MA46H500 through MA46H504 family has hyper-
abrupt junctions with constant gamma of 1.5 from 2 to 12
volts and high quality factor.
The MA46H200 through MA46H206 family has hyper-
abrupt junctions with constant gamma of 1.25 from 2 to
20 volts and higher quality factor.
The MA46H070 through MA46H073 family has hyper-
abrupt junctions with constant gamma of 0.75 from 0 to
20 volts and very high quality factor.
The MA46H200 through MA46H206 (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 bandwidth VCOs and VTFs where
the optimum combination of very wide tuning range and
high quality factor is required.
The MA46504 through MA46506 family has abrupt junc-
tions with constant gamma of 0.5 from 0 to 30 volts and
the highest quality factor.
Applications
The MA46H070 through MA46H073 (gamma 0.75) family
of constant gamma hyperabrupt GaAs tuning varactors
has quality factor approaching that of abrupt junction var-
actors, but higher capacitance change versus tuning volt-
age. These diodes are very well suited for narrower
bandwidth VCOs and VTFs where wide tuning range and
very high quality factor are required.
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 var-
actors have greatest capacitance change versus voltage at
the cost of slightly lower quality factor than the other
families of GaAs varactors.
The MA46504 through MA46506 (gamma 0.5) family of
constant gamma abrupt GaAs tuning varactors has the
highest quality factor. These diodes are very well suited
for narrower bandwidth VCOs and VTFs where highest
quality factor is of paramount concern.
