DESCRIPTION
The TC1401 is a GaAs Pseudomorphic High Electron Mobility Transistor (PHEMT) which has high linearity and
high Power Added Efficiency. The device is with via-hole processes to reduce the thermal resistance and
grounding inductance. The short gate length enables the device to be used in a circuit up to 20GHz. All devices
are 100% DC tested to assure consistent quality. Backside gold plating is compatible with standard AuSn
die-attach.

Note:
* For the tight control of the pinch-off voltage . TC1401’s are divided into 3 groups:
(1)
TC1401P0710
: Vp = -1.5V to -1.9V (2)
TC1401P0811
: Vp = -1.6V to -2.0V (3)
TC1401P0912
: Vp = -1.7V to -2.1V
In addition, the customers may specify their requirements.
