MAVR-000350-11410T

Overview

The MAVR-000350-11410T is a single hyperabrupt junction silicon tuning varactor diode manufactured by MACOM Technology Solutions. Designed for surface mount applications, it utilizes the SOD-323 plastic package with two pins. The device features an absolute maximum reverse voltage of 12 V and supports a forward current of 50 mA. It operates within a temperature range of -55 °C to +125 °C and dissipates up to 250 mW. This component is engineered for high capacitance ratio performance at low voltages, making it suitable for commercial wireless applications.

Feature Summary

• Ion-implanted hyperabrupt junction construction for superior C-V repeatability
• High capacitance ratio capability at low operating voltages
• High Q factor performance at low voltages
• Surface mount design in compact SOD-323 package

Applications

• Voltage controlled oscillators (VCOs)
• Voltage tuned filters
• Commercial wireless communication systems

Procurement Notes

Verify that the specific part number matches the required SOD-323 surface mount package configuration. Confirm that the 12 V reverse voltage rating aligns with the circuit's biasing requirements. Ensure compatibility with the intended frequency bands, as this series is designed for applications up to the 2.4 GHz WLAN band. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a high capacitance ratio at low voltages is critical for circuit efficiency. The SOD-323 package is appropriate for space-constrained designs requiring surface mount technology. Consider the 12 V limit when designing bias networks. The hyperabrupt junction profile offers better linearity compared to abrupt junctions, which may be beneficial for specific tuning applications.

Part Context

This varactor belongs to the MA4ST300 series, which includes various ion-implanted silicon tuning varactors available in SOT-23, SOT-323, and SOD-323 packages. The series is characterized by its suitability for commercial wireless applications and its ability to provide consistent capacitance-voltage characteristics across production batches due to the SPC process.

Replacement Considerations

Check the official datasheet for other members of the MA4ST300 series that share similar electrical characteristics but differ in package type or specific capacitance values. Verify pinout compatibility before substituting with any alternative surface mount varactor diodes.
