MAVR-001350-12790T

Overview

The MAVR-001350-12790T is a silicon hyperabrupt varactor diode from the MAVR-0013xx series, designed for low voltage and low series resistance applications. It features a nominal capacitance of 11.0 pF at 0.5 V reverse bias, with a minimum breakdown voltage of 12 V. The device offers a typical capacitance ratio of 3.20 (VR=0.5V to VR=3.0V) and a maximum series resistance of 1.00 Ω at 2.0 V. Packaged in an SC-79 surface mount plastic case, it utilizes UHCVD/ion-implanted technology for superior C vs. V repeatability.

Feature Summary

• Hyperabrupt silicon tuning varactor optimized for high capacitance ratio and high Q factor under limited supply voltages.
• SPC process ensures superior capacitance versus voltage repeatability across manufacturing batches.
• Available in lead-free surface mount plastic packages including SC-79, SOD-323, and SC-70 configurations.

Applications

• Wide band tuning circuits requiring operation at low battery voltages.
• Low phase noise oscillator designs where supply voltage is restricted to 5 volts or less.
• RF filter tuning applications demanding consistent capacitance variation over temperature.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package style and configuration details. Ensure compliance with RoHS directives and check for any recent product change notifications that may affect mounting instructions or material specifications before finalizing procurement orders.

Selection Notes

Select this component when low series resistance at low tuning voltages is critical for circuit efficiency. The MAVR-001350 variant provides a lower nominal capacitance compared to the 001320 or 001330 series, making it suitable for higher frequency tuning ranges. Confirm that the required capacitance ratio meets the design specifications for the intended voltage swing.

Part Context

This part belongs to the MAVR-0013xx series of silicon hyperabrupt varactor diodes manufactured by MACOM Technology Solutions. The series includes variants like MAVR-001320, MAVR-001330, and MAVR-001340, which differ primarily in their nominal capacitance values while sharing similar low voltage performance characteristics and packaging options.

Replacement Considerations

Direct replacements within the same series include MAVR-001320-12790T, MAVR-001330-12790T, and MAVR-001340-12790T. These share the SC-79 package but offer different nominal capacitances. Verify that the alternative part's capacitance range aligns with the circuit's tuning requirements.
