MAVR-045441-0287AT

Overview

The MAVR-045441-0287AT is a single silicon varactor diode from the MA4ST series, designed for high-frequency to ultra-high-frequency applications. It features an abrupt junction profile and is housed in a plastic surface-mount package with three terminals. The device operates within a reverse voltage range up to 30V and provides a nominal capacitance of 47pF at zero bias. It supports a minimum capacitance ratio of 9.5 and is RoHS compliant.

Feature Summary

• Hyperabrupt junction profile for linear tuning characteristics
• Silicon construction optimized for RF and microwave circuits
• Surface-mount packaging suitable for automated assembly

Applications

• Voltage-controlled oscillators (VCOs)
• RF tunable filters
• Phase-locked loops (PLLs)

Procurement Notes

Verify component authenticity through authorized MACOM distributors or direct manufacturer channels. Confirm RoHS compliance status and specific tape-and-reel specifications against current datasheet revisions before procurement. Ensure storage conditions align with semiconductor handling standards to prevent moisture sensitivity issues.

Selection Notes

Select this component when a hyperabrupt capacitance-voltage characteristic is required for wideband tuning applications. Evaluate the 47pF nominal capacitance and 30V reverse voltage rating against circuit requirements. Consider the SOT-23 compatible footprint for PCB layout constraints.
