DESCRIPTION
The TC1401N is a GaAs Pseudomorphic High Electron Mobility Transistor (PHEMT), which has high linearity
and high Power Added Efficiency. The device has no via holes in the source pads. The short gate length
characteristic 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.
