DESCRIPTION
The TC1801 is a Pseudomorphic High Electron Mobility Transistor (PHEMT) GaAs Power FET, Which has high
linearity and high Power Added Efficiency. The device is processed with a propriety via-hole process, which
provides low thermal resistance and low inductance. The short gate length enables the device to be used in circuits
up to 20 GHz. All devices are 100 % DC tested to assure consistent quality.Bond pads are gold plated for either
thermo-compression or thermo-sonic wire bonding. Backside gold plating is compatible with standard AuSn
die-attach. Typical applications include commercial and military high performance power amplifier.

* *For the tight control of the pinch-off voltage . TC1801’s are divided into 3 groups:
(1)TC1801P1519 : Vp = -1.5V to -1.9V (2) TC1801P1620 : Vp = -1.6V to -2.0V
(3)TC1801P1721 : Vp = -1.7V to -2.1V In addition, the customers may specify their requirements.
