Description Applications
M/A-COM 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 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 abrupt junctions with constant gamma of 0.5 from 0 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 varactors. 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. The MA46H070 through MA46H073 (gamma 0.75) family of constant gamma hyperabrupt GaAs tuning varactors has quality factor approaching that of abrupt junction varactors, but higher capacitance change versus tuning voltage.These diodes are very well suited for narrowerbandwidth VCOs and VTFs where wide tuning range and very high quality factor are required. The MA46504 through MA46506 (gamma 0.5) family ofconstant gamma abrupt GaAs tuning varactors has the highest quality factor. These diodes are very well suited for narrower bandwidth VCOs and VTFs where highest quality factor is of paramount concern.

1. Case parasitics (Cp and Ls) are given for most case styles along with case outlines in the appendix. The Cp values listed typically have tolerances of 0.02 pF. 2. The values guaranteed for gamma are measured on unpackaged chips. The total capacitance versus bias voltage curve will deviate slightly from the chip capacitance versus bias voltage curve due to the package parasitic capacitance (Cp). 3. Capacitance is measured at 1 MHz. 4. Reverse voltage (VB) is measured at 10 microamps. 5. The total capacitance and capacitance ratios shown are for diodes housed in case style 30. Other case styles will result in different values. 6. When ordering MA46H202-134 as whole wafer P/N is MAVR-0046202-0134WR
