MACOM offers four 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 MA46H200 through MA46H204 family has
hyperabrupt junctions with constant gamma of 1.25
from 2 to 20 volts and higher quality factor.
The MA46H200 through M46H204 (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.
