General Description

SAC3903 is a GaAs MMIC driver amplifier die covering 0.9 to 1.3 GHz with 36 dB of gain. Output P1dB is 25.5 dBm and OIP3 is 36 dBm.

Noise figure is 3.2 dB, gain flatness 0.9 dB, and VSWR 1.8:1 at both ports. The +8 V supply draws 162 mA, and the die is 1.3 x 1.25 x 0.1 mm. Getting 36 dB from one chip can save a gain stage in EW, SATCOM, cellular infrastructure and beamforming chains.
