General Description

SAC3911 is a low-current GaAs MMIC driver amplifier die for 24 to 40 GHz with a balanced layout. It provides 12 dB of gain flat to ±1.0 dB, 15 dBm output P1dB and a 5 dB noise figure.

Current draw is only about 60 mA, from a +4 to +6 V drain supply. Both ports sit around 1.4:1 VSWR (roughly 15 dB return loss). The passivated die measures 1.67 x 1.22 x 0.1 mm. Moderate gain and low DC power suit it to LO driver and linear gain block duty in Ka-band radios and SATCOM.
