General Description

SAC3912 is a balanced GaAs MMIC amplifier die for 20 to 38 GHz, meant as a linear gain block or LO driver. It has 8 dB of gain within ±1.5 dB, 18 dBm output P1dB and a 5 dB noise figure.

Supply is +5 to +6 V at roughly 100 mA. Because it is balanced, input and output stay near 1.3:1 VSWR whether biased or not, so it cascades cleanly between filters and mixers. The die is 1.67 x 1.22 x 0.1 mm with full passivation. Common sockets include point-to-point radios, SATCOM and test gear.
