Flange Ceramic Package
DESCRIPTION
The TC2491 is packaged with the TC1401 Pseudomorphic High Electron Mobility Transistor (PHEMT) chip.
The flange ceramic package provides the best thermal conductivity for the GaAs FET. All devices are 100%
DC and RF tested to assure consistent quality. Typical applications include high dynamic range power
amplifiers for commercial and military high performance power applications.

** For the tight control of the pinch-off voltage range, we divide TC2491 into 3 model numbers to fit customer design requirement
(1)TC2491P1519 : Vp = -1.5V to -1.9V (2)TC2491P1620 : Vp = -1.6V to -2.0V (3)TC2491P1721 : 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.
