DESCRIPTION
The TC2471 is packaged with the TC1401 Pseudomorphic High Electron Mobility Transistor (PHEMT) chip. The
Cu-based ceramic package provides excellent thermal conductivity for the GaAs FET. All devices are 100% DC
tested to assure consistent quality. Typical applications include high d
ynamic range power amplifiers for
commercial and military high performance power applications .

For the tight control of the pinch-off voltage range, we divide TC2471 into 3 model numbers to fit customer design requirement
(1)TC2471P1519 : Vp = -1.5V to -1.9V (2)TC2471P1620 : Vp = -1. 6V to -2.0V (3)TC2471P1721 : Vp = -1.7V to -2.1V
If required, customer can specify the requirement in purchasing document. For special Vp requirement, please contact factory for details.
