MAVR-011020-14110G

Overview

The MAVR-011020-14110G is a single-polarity gallium arsenide (GaAs) hyperabrupt varactor diode designed for flip-chip surface-mount applications. It features a constant gamma characteristic to support linear tuning requirements in RF circuits. The device operates within a junction temperature range of -40°C to +125°C and is rated for a maximum peak reverse voltage of 22 V. Key electrical parameters include a capacitance of 0.05 pF at 15 V and 1 MHz, and a quality factor of 3000 at 4 V and 50 MHz. It is housed in a compact 2-XFDFN or FCDFN package.

Feature Summary

• Hyperabrupt doping profile with constant gamma for linear tuning
• Flip-chip GaAs construction for high cutoff frequency
• Single-polarity design suitable for compact RF layouts

Applications

• Voltage-controlled oscillators (VCOs)
• Phase-locked loops (PLLs)
• Frequency multipliers
• Tunable RF filters

Procurement Notes

Verify the specific suffix 'G' against the manufacturer datasheet to confirm packaging or material compliance differences compared to the 'P' variant. Ensure ESD handling protocols are followed during assembly due to the flip-chip configuration. Cross-reference the PCN documents for any recent changes in tape and reel specifications or marking updates before finalizing procurement orders.

Selection Notes

Select this component when a low capacitance value and high Q-factor are required for high-frequency linear tuning applications. The 22 V reverse voltage rating suits moderate voltage swing environments. Compare the 0.05 pF minimum capacitance against circuit requirements to ensure adequate tuning range. Verify that the flip-chip footprint matches the PCB land pattern design guidelines provided in the official datasheet.
