General Description

SAC3913BQ4 is a GaAs MMIC driver amplifier for 7.9 to 9 GHz, assembled in a 4 x 4 mm air cavity QFN. Gain is 24 dB with ±1 dB flatness, output P1dB is 28 dBm, and OIP3 is 33 dBm at 30% PAE.

A single +8 V drain supply at about 230 mA runs it. Input VSWR is 1.3:1 and output VSWR is 1.8:1. The 4 x 4 x 1.2 mm air cavity package makes it a reflow-friendly part for lower X-band radar and SATCOM transmit boards.
