DESCRIPTION
The TC1706 is a GaAs Pseudomorphic High Electron Mobility Transistor (PHEMT), 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 long gate length makes the device to have high breakdown voltage.
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 amplifiers.

For the tight control of the pinch-off voltage . TC1706’s are divided into 3 groups:
(1)
TC1706P1519
: Vp = -1.5V to -1.9V (2)
TC1706P1620
: Vp = -1.6V to -2.0V
(3)TC1706P1721 : Vp = -1.7V to -2.1V In addition, the customers may specify their requirements.
