General Description

SAC3937AQP4 is a self-biased GaAs MMIC driver amplifier for 0.03 to 3 GHz in a RoHS compliant, low stress molded 4 x 4 mm QFN. It reaches 30 dBm output P1dB (29 dBm minimum) with 16 dB of gain held to ±0.5 dB.

Since it biases itself, a single +12 V rail at about 450 mA is all it needs; input VSWR is 1.5:1. The package is 0.75 mm thick, and a 1.25 x 1.55 x 0.1 mm bare die version is listed. Works as a 1 W class IF amp or PA driver.
