TC3131 REV2_20040412 2.4 GHz 1W MMIC FEATURES PHOTO ENLARGEMENT • P-1 dB: 30 dBm • Small Signal Gain: 28 dB • Power Added Efficiency: 32 % • IP3: 39 dBm • Bias Condition: 400 mA @ 7 V GND RF OUT Vg RF OUT GND Vd RF IN GND DESCRIPTION The TC3131 is a 2 stage PHEMT MMIC power amplifier. It is designed for use in low cost and high volume 2.4-2.5 GHz ISM band applications. The MMIC provides a typical gain of 26 dB and saturation power of more than 30 dBm. Typical bias condition is 7V at 400 mA. The MMIC is packaged in a standard SO-8 power package. The copper based carrier of the package allows direct soldering of the device to the PCB for proper heat sinking. The input and output matching of the MMIC require external components.
