High Linearity: IP3 = 47 dBm Typical at 6 GHz ! Via Holes Source Ground ! Suitable for High Reliability Application ! Breakdown Voltage: BVDGO ≥ 15 V ! Lg = 0.35 µm, Wg = 12 mm ! High Power Added Efficiency: PAE ≥ 40 % for Class A Operation ! Tight Vp ranges control ! High RF input power handling capability ! 100 % DC Tested 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.
