MAVR-000405-0287AT

Overview

The MAVR-000405-0287AT is a single hyperabrupt junction silicon tuning varactor from the MAVR-000400 Series, manufactured by MACOM Technology Solutions. It utilizes ion implantation for high quality factor and capacitance ratio performance. The device is housed in an SOT-23 surface mount package (Case Style 287) with matte tin plating. Electrical specifications at TA = +25°C include a nominal total capacitance of 22.0 pF, a minimum capacitance ratio of 7.5, and a typical Q factor of 175 at 50 MHz. 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 for high quality factor and capacitance ratio
• SPC monitored ion implantation ensures excellent C-V repeatability
• Surface mount construction in SOT-23 package with matte Sn plating

Applications

• Octave bandwidth tuning in HF to UHF frequency bands
• Voltage controlled oscillators (VCOs)
• Voltage tuned filters in radios and cable TV tuners
• Test instruments requiring 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 account for electrostatic discharge sensitivity during storage and assembly processes.

Selection Notes

Select this part for applications requiring octave bandwidth tuning within the HF to UHF ranges. Consider the nominal 22.0 pF capacitance and 7.5 capacitance ratio when designing circuits. Evaluate thermal constraints against the 250 mW power dissipation limit and ensure operating temperatures remain within the -55°C to +125°C range.
