MA46 Series Surface Mount GaAs Tuning Varactors Rev. V8 0.75, 1.25, & 1.5 Gamma Hyperabrupt Features Common Case styles Gamma Hyperabrupt Junctions: 0.75, 1.25 and 1.5 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 1056 1088 Description MACOM offers three families of low cost surface mount gallium arsenide tuning varactors. All families have silicon nitride protected junctions for low leakage current and high reliability. Packaged Tuning Varactor Equivalent Circuit The MA46H070 through MA46H073 family has hyperabrupt junctions with constant gamma of 0.75 from 0 to 20 volts and very high quality factor approaching that of abrupt junction varactors, but higher capacitance change versus tuning voltage. These diodes are very well suited for narrow bandwidth VCOs and VTFs where wide tuning range and very high quality factor are required. The MA46H200 through MA46H204 family has hyperabrupt junctions with constant gamma of 1.25 from 2 to 20 volts and has the largest capacitance ratio of the families of GaAs varactors and high 1,2 quality factor. These diodes are very well suited for Absolute Maximum Ratings wide bandwidth VCOs and VTFs where the optimum Absolute Maximum combination of very wide tuning range and high Parameter quality factor is required. Case 1056 Case 1088 The MA46H500 through MA46H504 family has Operating Temperature -65C to +150C -65C to +125C hyperabrupt junctions with constant gamma of 1.5 from 2 to 12 volts and high quality factor. Designed Storage Temperature -65C to +200C -65C to +125C for wide bandwidth VCOs and VTFs where limited bias voltage is available. These varactors have Reverse Voltage Breakdown Voltage lower quality factor than the other families of GaAs varactors. Forward Current 50 mA 25C 50 mW 25C, Power Dissipation de-rate linearly to 0 mW maximum operating temperature 1. Exceeding any one or combination of these limits may cause permanent damage to this device. 2. MACOM does not recommend sustained operation near these survivability limits. 11 1 M/A-COM Technology Solutions Inc.

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). 4. The Cp values listed typically have tolerances of 0.02 pF. 5. Capacitance is measured at 1 MHz. 6. The total capacitance and capacitance ratios shown are for diodes housed in case style 30. Other case styles will result in different values. 7. When ordering MA46H202-134 as whole wafer P/N is MAVR-0046202-0134WR. 22 2 M/A-COM Technology Solutions Inc.
