MACOM offers three families of low cost surface
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
