TAV-541+

Overview

The TAV-541+ is an Enhancement mode Pseudomorphic High Electron Mobility Transistor (E-PHEMT) designed for ultra-low noise and high linearity applications. It operates across a wide bandwidth from 0.045 to 6 GHz, utilizing a single positive supply voltage. The device features a small MCLP package measuring 1.18 x 1.42 x 0.85 mm. Key electrical specifications include a typical Noise Figure of 0.5 dB at 2 GHz, Gain of 17 dB at 2 GHz, Output IP3 of +33 dBm, and Power output at 1dB compression of +19 dBm. It requires external biasing and matching components.

Procurement Notes

Verify the RoHS compliance status by checking the datasheet or manufacturer website, as indicated by the plus suffix. Confirm that the ordering suffix accurately reflects the lead-free plating requirements. Ensure the component matches the specified case style and package dimensions for your PCB layout. Validate the electrical parameters against the latest revision of the official datasheet before finalizing procurement.

Selection Notes

Select this component when designing amplifiers requiring ultra-low noise figures below 2.5 GHz combined with high linearity. It is suitable for base station applications demanding high gain and high output IP3. Designers must provide external DC biasing circuits and impedance matching networks, as the device does not include integrated stabilization or matching components. Consider the thermal resistance and operating temperature range for heat dissipation planning.
