MAVR-000407-0287FT

Overview

The MAVR-000407-0287FT is a surface mount hyperabrupt junction silicon tuning varactor from the MAVR-000400 Series, manufactured by MACOM Technology Solutions. It is housed in an SOT-23 package and features thermal oxide passivation with ion-implanted construction for excellent C-V repeatability. The device operates as a common cathode pair configuration. Key electrical specifications include a nominal total capacitance of 33 pF (range 29.7–36.3 pF), a typical capacitance ratio of 9.0 at 50 MHz, and a maximum reverse current of 15 nA at 30 V. Absolute maximum ratings specify a reverse voltage of 30 V, forward current of 50 mA, and power dissipation of 250 mW.

Feature Summary

• Ion-implanted hyperabrupt junction design providing high quality factor and capacitance ratios up to 9.5:1
• Common cathode pair configuration within a compact SOT-23 surface mount package
• SPC monitored ion implantation ensures consistent capacitance-voltage characteristics across lots
• RoHS compliant with 100% matte tin plating and tape and reel packaging availability

Applications

• Voltage controlled oscillators (VCOs) requiring octave bandwidth tuning
• Voltage tuned filters in radio communication systems
• Cable TV tuners and test instruments demanding low cost and lot-to-lot repeatability

Procurement Notes

Verify component authenticity through authorized MACOM distributors or direct channels. Confirm RoHS compliance status and specific packaging requirements such as tape and reel quantities. Ensure handling procedures adhere to electrostatic discharge (ESD) precautions due to device sensitivity. Cross-reference datasheet revision V6 for accurate electrical parameters before finalizing procurement orders.

Selection Notes

Select this part when a common cathode configuration is required for differential tuning or balanced circuit topologies. The 33 pF nominal capacitance suits HF to UHF applications where moderate tuning ranges are needed. Compare against single diode variants like the MAVR-000407-0287AT if independent control is preferred. Evaluate the 9.0 capacitance ratio against system linearity requirements within the 3 to 8 volt linear tuning range.

Part Context

This component belongs to the MAVR-000400 Series of surface mount hyperabrupt varactors. The series includes various capacitance values ranging from 10 pF to 47 pF, available in both single and common cathode configurations. The suffix 'FT' specifically denotes the common cathode pairing and RoHS compliant packaging style, distinguishing it from the 'AT' single diode variant.

Replacement Considerations

Direct functional equivalents within the same series include the MAVR-000407-0287AT for single diode applications. For common cathode replacements with identical electrical characteristics, verify availability of other MAVR-000400 series FT suffix parts. Ensure pinout compatibility and package dimensions match the existing PCB layout when substituting.
