General Description

SAC3935 is a balanced GaAs MMIC driver amplifier die for Q band, 42 to 47 GHz. It provides 18 dB of gain (±2 dB), 20 dBm typical output P1dB with 18 dBm guaranteed minimum, and 27 dBm OIP3 at 44 GHz.

Thanks to the balanced topology, both ports hold 1.6:1 VSWR, which helps when cascading at millimeter-wave. Bias is +5 V drain with a negative gate voltage at 200 mA. The passivated die is 2.1 x 1.25 x 0.1 mm, sized for wireless infrastructure radios and high density MCM components.
