General Description

SAC3930Q3 is a VHF to L-band GaAs MMIC driver amplifier, 0.05 to 1.5 GHz, in a 3 x 3 x 1.2 mm leadless QFN. It offers 12 dB gain within ±1 dB, 2.5 dB noise figure, 18 dBm output P1dB at 1 GHz and 36 dBm OIP3.

Linearity is the selling point here: 36 dBm OIP3 on just 80 mA from one +5 V rail. Gain-temperature compensation is built in, and input and output VSWR are both 1.5:1. Works well as a low noise gain block early in a communication receiver.
