Overview
The MAVR-011005-12790T is a surface-mount GaAs hyperabrupt tuning varactor diode designed for applications requiring wide tuning ranges and high quality factors. It features a constant gamma characteristic from 2 to 12 volts. The device is housed in an RoHS-compliant plastic SC-79 package with minimal parasitic inductance of 0.6 nH. Key electrical specifications include a typical capacitance (Ct) of 0.270 pF, a breakdown voltage minimum of 20 V at 10 µA reverse current, and a maximum reverse leakage current of 100 nA at 10 V. Capacitance ratios are typically 1.8 between 4 V and 12 V reverse bias.
Feature Summary
- Hyperabrupt tuning profile providing consistent gamma characteristics across the operating voltage range
- Small profile SC-79 surface mount package designed for minimal parasitic inductance
- High quality factor capability suitable for demanding tuning applications
Applications
- Wide tuning range oscillator circuits
- Phase-locked loop (PLL) frequency synthesizers

Procurement Notes
Verify component authenticity through authorized MACOM Technology Solutions distributors or direct channels. Confirm datasheet revision status and engineering sample availability if volume production commitment is pending. Ensure packaging matches tape and reel requirements for automated assembly processes.
Selection Notes
Select this component when low parasitic inductance and high Q-factor are critical for circuit performance. Evaluate thermal limits against absolute maximum ratings during operation. Consider the SC-79 package dimensions for PCB layout constraints and soldering temperature profiles compatible with RoHS compliant devices.
Part Context
This part belongs to the MAVR series of surface-mount GaAs tuning varactors manufactured by MACOM Technology Solutions. The series focuses on hyperabrupt junction designs optimized for RF and microwave tuning applications where size and electrical performance are prioritized.
Replacement Considerations
Cross-reference with other MACOM MAVR series variants offering similar SC-79 packaging. Verify that substitute components maintain equivalent capacitance ratios and parasitic inductance values to ensure circuit stability without redesign.
