Overview
The MGV075-08-0805-2 is a packaged GaAs hyperabrupt varactor diode from the MGV075-x series, manufactured by MACOM Technology Solutions. It features a 0.75 constant gamma characteristic and utilizes passivated mesa construction for low leakage current and stable post-tuning performance. The device operates with a tuning voltage range of 0 to 18 V and supports tuning ratios up to 10. Electrical specifications are measured at TA = +25°C, VB = 18 V min., and IR = 100 nA max. At VR = 4 V and 1 MHz, the total capacitance ranges from 0.30 pF (min) to 0.42 pF (max), with a nominal value of 0.36 pF. The minimum Q factor is 4,000 at 50 MHz.
Feature Summary
- Passivated mesa construction ensures low leakage and excellent post-tuning drift stability.
- Available in packaged form screened per MIL-PRF-19500 and MIL-PRF-35834 standards.
- Designed for high-frequency applications including tunable filters and oscillators up to 40 GHz.
Applications
- Tunable RF filters
- Voltage-controlled oscillators (VCOs)
- Phase-locked loops (PLLs)
Procurement Notes
Verify component authenticity through authorized MACOM distributors or direct channels. Confirm RoHS compliance status and check for specific screening options under MIL-PRF-19500 or MIL-PRF-35834 if required for your application. Ensure ordering suffixes match the desired package style and screening level.
Selection Notes
Select this model based on the required nominal capacitance of 0.36 pF and the need for a 0.75 constant gamma profile. Consider the packaged 0805-2 outline for surface-mount integration. Evaluate the Q factor of 4,000 at 50 MHz against circuit requirements. Compare against other MGV075 variants if different capacitance values or packaging styles are needed.
Part Context
This component belongs to the MGV075-x family of GaAs hyperabrupt varactor diodes. The series includes three constant gamma families: 0.75, 1.0, and 1.25. Other models in the 0.75 family include MGV075-08 through MGV075-17, available in chip (C01A) and various packaged formats such as E28, H20, P55, and 0805-2.
Replacement Considerations
Direct replacements within the same constant gamma family include MGV075-08-E28, MGV075-08-H20, and MGV075-08-P55. For different capacitance needs, consider adjacent models like MGV075-09-0805-2. Alternative gamma profiles require switching to the MGV100-x or MGV125-x series.
