Description Applications M/A-COM offers four families of low cost surface mount gallium arsenide tuning varactors. All fami-lies 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 MA46H200 through MA46H204 family has hyperabrupt junctions with constant gamma of 1.25 from 2 to 20 volts and higher quality factor. The MA46H070 through MA46H073 family has hyperabrupt junctions with constant gamma of 0.75 from 0 to20 volts and very high quality factor. The MA46504 through MA46506 family has to 30 volts and the highest quality factor. Applications 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 Features Constant Gamma Abrupt Junction: 0.5 Hyperabrupt Junctions: 0.75, 1.25 and 1.5 Low Cost Surface Mount Packages Very High Quality Factor Capacitance Ratio to 10:1 Case Style 1056 is Hermetic and may be Screened to JANTX levels Tape and Reel Packaging Available Description Applications M/A-COM offers four families of low cost surface mount gallium arsenide tuning varactors.
