DESCRIPTION
The TC3943 is a Single-bias and prematched GaAs PHEMT. It is designed for use in low cost, high volume, and 5~10 GHz 0.5W amplifiers. It provides a typical gain of 7dB and P1dB of 27dBm at 10GHz. The single positive drain bias is 8V and the typical drain-source current is 150mA. The device is packaged in copper based ceramic 10 pins SMT packages. The copper based carrier of the package allows direct soldering of the device to the PCB.
