General Description

SAC3955 is a GaAs MMIC driver amplifier die with a balanced design, spanning 47 to 58.5 GHz with 15 dB of gain and 20 dBm output P1dB.

At only 200 mA from +5 V (plus negative gate bias) it is a fairly low power way to drive a V-band PA or mixer. Flatness is ±1.5 dB, NF is 10 dB, both ports hold 1.35:1 VSWR, and the passivated die is 2.3 x 1.24 x 0.1 mm. Used in point to point radio and satcom hardware.
