MGV-075-10-H27

Overview

The MGV-075-10-H27 is a Gallium Arsenide (GaAs) hyperabrupt varactor diode from the MGV075-x series, characterized by a constant gamma of 0.75. It features a passivated mesa construction designed for low leakage and excellent post-tuning drift stability. The device operates within a tuning voltage range of 0 to 18 V and supports tuning ratios up to 10. Electrical specifications at TA = +25°C and VR = 4 V include a nominal total capacitance of 0.50 pF with a minimum Q factor of 3,000 at 50 MHz. The H27 suffix indicates a specific packaged configuration available in screened versions.

Feature Summary

• Passivated mesa construction ensures low leakage current and stable performance after tuning.
• Constant gamma value of 0.75 enables predictable frequency tuning characteristics.
• Available in screened configurations compliant with MIL-PRF-19500 and MIL-PRF-35834 standards.

Applications

• Tunable filters operating up to 40 GHz
• Voltage-controlled oscillators (VCOs)
• Microwave phase shifters

Procurement Notes

Verify the exact package type associated with the H27 suffix against the manufacturer's official documentation before ordering. Confirm that the screening requirements align with project specifications, as military-grade screening per MIL-PRF-19500 or MIL-PRF-35834 may be optional depending on the specific sub-part number variant.

Selection Notes

Select this component when a constant gamma of 0.75 is required for specific circuit linearity needs. Compare the 0.50 pF nominal capacitance against circuit requirements at 4 V bias. Ensure the design can accommodate the specified Q factor limits at 50 MHz and verify that the packaging style meets the thermal and mechanical constraints of the assembly process.

Part Context

This part belongs to the MGV075-x family of GaAs hyperabrupt varactors. Other members in this family offer different nominal capacitances ranging from 0.25 pF to 2.20 pF. Alternative families within the same product line provide constant gammas of 1.0 (MGV100-x) and 1.25 (MGV125-x) for varying tuning curve requirements.

Replacement Considerations

Direct replacements within the same constant gamma family include other MGV075-x variants with adjusted capacitance values. For different tuning characteristics, consider the MGV100-x series (gamma 1.0) or MGV125-x series (gamma 1.25). Verify pinout and package dimensions match before substituting.
