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 MA46H500 through MA46H504 family has
hyperabrupt junctions with constant gamma of 1.5
from 2 to 12 volts and high quality factor.
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
factor than the other families of GaAs varactors
