General Description

SAC3913 is an X-band GaAs MMIC driver amplifier die covering 8 to 13 GHz with 32.5 dBm output P1dB. Gain is 19 dB (±2 dB) and power-added efficiency reaches 35% at compression.

Run it from +5 to +6 V on the drain; quiescent current is about 650 mA, and the gate takes a negative bias. Port VSWR is 1.4:1. The passivated die is 2.01 x 1.25 x 0.1 mm. That much output at 35% PAE lets it drive a high power stage, or serve as the final amplifier, in X-band radar and SATCOM transmitters.
