MA46474-95

Overview

The MA46474-95 is a Gallium Arsenide (GaAs) hyperabrupt variable capacitance diode designed for Very High Frequency to Ka Band applications. It belongs to the MA46410 through MA46480 series, characterized by a constant gamma of 1.25. The device features a nominal junction capacitance of 1 pF with a tolerance of 10% and a minimum breakdown voltage of 22 V. It offers a high quality factor, reaching up to 4000 at -4 Volts, and provides linear frequency tuning with nearly constant modulation sensitivity. The component is housed in a ceramic package and complies with RoHS standards.

Feature Summary

• Hyperabrupt junction design with constant gamma of 1.25 for linear frequency tuning
• High quality factor performance suitable for RF and microwave circuits
• Lead-free construction compliant with environmental regulations

Applications

• Voltage-controlled oscillators (VCOs)
• Frequency multipliers
• Tunable RF filters

Procurement Notes

Verify the specific suffix '-95' against official MACOM documentation to confirm packaging or reflow compatibility details. Ensure that the procurement channel sources the component directly from authorized distributors to guarantee authenticity and traceability of the GaAs material properties.

Selection Notes

Select this component when a constant gamma of 1.25 is required for linear tuning characteristics in VHF to Ka Band designs. Consider the 1 pF nominal capacitance and 22 V breakdown voltage limits during circuit biasing. Evaluate thermal management requirements as the device operates within standard semiconductor temperature ranges.

Part Context

This part is part of the MA464xx series of GaAs hyperabrupt varactor diodes manufactured by MACOM Technology Solutions. The series includes variants with different gamma constants (1.0, 1.25, 1.5) to suit various linearity and tuning range requirements in high-frequency electronic systems.

Replacement Considerations

Check for equivalents within the MA46410, MA46450, and MA46470 series if different gamma values are acceptable. Verify pinout and package dimensions before substituting with other manufacturers' hyperabrupt varactors.
