Overview
The MAVR-000407-0287AT is a single hyperabrupt junction silicon tuning varactor from the MAVR-000400 Series, manufactured by MACOM Technology Solutions. It utilizes ion implantation for high capacitance ratio and quality factor, packaged in an SOT-23 (Case Style 287) surface mount configuration. The device operates within the HF to UHF frequency bands with a nominal total capacitance of 33.0 pF at 4V reverse bias. Key electrical specifications include a minimum capacitance ratio of 9.0, a Q factor of 150 at 50 MHz, and a maximum reverse current of 15 nA at 30V. 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 capacitance ratio and quality factor
- SPC monitored ion implantation ensures excellent C-V repeatability and lot-to-lot consistency
- Surface mount construction in SOT-23 package with matte Sn plating
Applications
- Voltage controlled oscillators (VCOs)
- Voltage tuned filters in radios and cable TV tuners
- Octave bandwidth tuning applications in test instruments
Procurement Notes
Verify component authenticity through authorized MACOM distributors or direct manufacturer 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 when a single diode configuration with a nominal 33pF capacitance is required for HF to UHF tuning circuits. Consider the MAVR-000407-0287FT variant if a common cathode pair topology is necessary for differential applications. Evaluate thermal constraints against the 250mW power dissipation limit.
Part Context
This component belongs to the MAVR-000400 Series of surface mount hyperabrupt varactors. The series includes variants ranging from MAVR-000401 to MAVR-000409, offering different capacitance values from approximately 10pF to 47pF. Other configurations include common cathode pairs and alternative SC-79 packages.
Replacement Considerations
Direct substitutes are not explicitly listed in the provided documentation. Equivalent components must match the 33pF nominal capacitance, SOT-23 package, and hyperabrupt junction characteristics. Verify that any replacement meets the same absolute maximum ratings and RF performance metrics.
