MGV-075-10-P55

Overview

The MACOM MGV-075-10-P55 is a packaged GaAs hyperabrupt varactor diode belonging to the 0.75 constant gamma family, designed for tunable filters and oscillators up to 40 GHz. It features passivated mesa construction for low leakage and excellent post-tuning drift. Electrical specifications at TA = +25°C, VB = 18 V min., and IR = 100 nA max. define its performance. Total capacitance at VR = 4 V, 1 MHz ranges from 0.56 pF (min) to 0.70 pF (max), with a nominal value of 0.63 pF. Tuning ratios are 1.5 (min), 2.1 (typ), and 2.7 (typ) for VR = 2 to 12 V, and 1.5, 2.1, and 2.7 for VR = 2 to 18 V. Quality factor at VR = 4 V, 50 MHz is 3,000 (min). The P55 package adds 0.13 pF capacitance and 0.35 nH inductance at 1 GHz.

Feature Summary

• Passivated mesa construction ensures low leakage current and stable post-tuning characteristics.

Applications

• Tunable microwave filters
• Voltage-controlled oscillators

Procurement Notes

Verify component authenticity through authorized distribution channels or direct manufacturer confirmation. Request official datasheets and material compliance certificates prior to procurement. Ensure storage conditions align with semiconductor handling standards to prevent electrostatic discharge damage. Confirm packaging type matches design requirements before finalizing orders.

Selection Notes

Select this variant when a nominal total capacitance near 0.63 pF is required for circuits operating within the specified frequency range. The P55 package provides specific parasitic parameters suitable for certain board layouts. Evaluate tuning ratio requirements against circuit bandwidth needs. Consider thermal management strategies as electrical specifications assume a +25°C ambient temperature.
