DESCRIPTION
The TC3341 is a 2-stage PHEMT MMIC power amplifier. It is designed for use in low cost and high volume 3.3-3.7 GHz band applications. The MMIC is matched to 50Ω operation. It provides a typical gain of 27 dB and P1dB power of 32.5 dBm. Typical bias condition is 8V at 700 mA. The MMIC is 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.
