TC3531 REV4_20060525 5.8 GHz 1W MMIC FEATURES • • • • • • P-1 dB: 30 dBm Small Signal Gain: 24 dB Power Added Efficiency: 24 % IP3: 39 dBm Match to 50 Ω Operation Bias condition: 600 mA @ 7 V PHOTO ENLARGEMENT Vg1 GND GND RF IN Vd1 Vd2 Vg2 RF OUT NC GND DESCRIPTION The TC3531 is a 2 stage PHEMT MMIC power amplifier. It is designed for use in low cost and high volume 5.7-5.9 GHz band applications. The MMIC is matched to 50 Ω operation. No external matching component is required. It provides a typical gain of 24 dB and P1 dB power of 30 dBm. Typical bias condition is 7V at 600 mA. The MMIC is a packaged in a copper based ceramic 10 pins power package. The copper based carrier of the package allows direct soldering of the device to the PCB for proper heat sinking.
