DESCRIPTION
The TC1601 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.
