TAV-581+

Overview

The TAV-581+ is an enhancement mode pseudomorphic high electron mobility transistor (E-PHEMT) designed for ultra-low noise and medium current applications. It operates with a single positive supply voltage, offering a typical noise figure of 0.5 dB at 2 GHz and a gain of 17 dB. The device provides a high output IP3 of +31 dBm and an output power at 1dB compression of +19 dBm while consuming only 30 mA of drain current. It supports wide bandwidth operation from 0.45 to 6 GHz.

Feature Summary

• Utilizes E-PHEMT technology for low noise performance and compatibility with single positive supply voltages
• Delivers high linearity characterized by high output IP3 and significant output power at 1dB compression
• Features low quiescent current consumption suitable for power-sensitive designs
• Provides wide bandwidth coverage across the 0.45 to 6 GHz frequency range

Applications

• Cellular base stations
• ISM band amplifiers
• GSM systems
• WCDMA infrastructure
• WiMax networks

Procurement Notes

Verify RoHS compliance status as indicated by the plus suffix in ordering information. Confirm package dimensions against Case Style FG873 specifications during integration. Ensure external biasing networks are designed to maintain the specified 30 mA drain current for optimal noise and linearity performance. Check datasheet maximum ratings for VDS and VGS limits to prevent permanent damage.

Selection Notes

Select this component when designing amplifiers requiring minimal signal degradation in the 0.45 to 6 GHz range. The device is ideal for base station front-ends where low noise figure and high linearity must coexist. Designers must provide external matching and bias circuits; consider Mini-Circuits TAMP or RAMP series modules if integrated solutions are preferred over discrete design.
