TC3133 REV2_20031121 2.4 GHz 1W MMIC FEATURES PHOTO ENLARGEMENT • P-1 dB: 31 dBm Vg GND • Small Signal Gain: 24 dB NA RF OUT • Power Added Efficiency: 30 % RF IN RF OUT • IP3: 39 dBm GND Vd • Bias Condition: 600 mA @ 5 V DESCRIPTION The TC3133 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 24 dB and saturation power of more than 31 dBm. Typical bias condition is 5V at 600 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.
