GaAs Hyperabrupt

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.
