ATF-13170 is a kind of high performance gallium arsenide Schottky-barrier-gate field effect transistor housed in a hermetic and high reliability package.Its premium noise figure makes this device appropriate for use in the first stage of low noise amplifiers operating in the 2-16 GHz frequency range.There are some features as follows.First is low noise figure:1.0 dB typical at 12 GHz.Then is high associated gain:10.0 dB typical at 12 GHz.Next is high output power:17.5 dBm typical P1 dB at 12 GHz.The last one is hermetic gold-ceramic microstrip package.
What comes next is about the absolute maximum ratings.The VDS (drain-source voltage) is +5 V.The VGS (gate-source voltage) is -4 V.The IDS (drain current) is IDSS.The PT (power dissipation) is 225 mW.The TCH (channel temperature) is 175.The TSTG (storage temperature) is from -65 to +175.
