PHOTO ENLARGEMENT
DESCRIPTION
The TC3139 is a 2 stage PHEMT MMIC power amplifier. It is designed for use in low cost, high volume,
2.3 –2.5 GHz band applications. The MMIC provides a typical gain of 26 dB and P1dB power of more than 30
dBm. Typical bias condition is 7V at 400 mA. The MMIC is packaged in a low-cost surface-mountable plastic
package. The input and output matching of the MMIC require minimum external components.
