General Description

SAC3947QP3 is a 0.03 to 2 GHz GaAs MMIC driver amplifier in a 3 x 3 mm QFN. At 1 GHz it shows 40 dBm OIP3, 50 dBm OIP2 and only 1.7 dB noise figure, with 17 dB of gain and 27 dBm output P1dB.

Low noise plus strong second and third order linearity lets it work in receive as well as transmit lineups. Gain temperature compensation is built in, flatness is ±0.75 dB, and it needs one +8 V supply at 270 mA. Fits SDR, point to point radio and satcom IF stages.
