MAVR-000409-0287FT

Overview

The MAVR-000409-0287FT is a surface mount hyperabrupt junction silicon tuning varactor from the MAVR-000400 Series, manufactured by MACOM Technology Solutions. It features a common cathode configuration with two diodes in a single SOT-23 package (Case Style 287). The nominal total capacitance is 47 pF at 4 V reverse bias, with a typical capacitance ratio of 9.5:1 and a quality factor of 150 at 50 MHz. The device supports a maximum reverse voltage of 30 V and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Common cathode dual-diode configuration for octave bandwidth tuning
• Hyperabrupt junction design providing high capacitance ratio
• SOT-23 surface mount package with thermal oxide passivation

Applications

• Voltage controlled oscillators (VCOs)
• Voltage tuned filters in radios
• Cable TV tuners
• Test instruments requiring linear tuning performance

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the package style, internal configuration, and packaging requirements. Ensure that the selected variant matches the required circuit topology and environmental specifications before procurement.

Selection Notes

Select this component when a common cathode arrangement is required for HF to UHF applications. Evaluate the nominal capacitance and Q-factor against the target frequency band. Confirm that the operating voltage range aligns with the available linear tuning performance characteristics.

Part Context

This part belongs to the MAVR-000400 Series of ion-implanted hyperabrupt varactors. The series includes both single diode and common cathode pair configurations across various capacitance values, all utilizing SOT-23 or SC-79 packages.

Replacement Considerations

Other parts in the MAVR-000400 series, such as the MAVR-000409-0287AT, offer identical electrical parameters but utilize a single diode configuration instead of a common cathode pair.
