General Description

SAC3147Q6 is a C-band GaAs MMIC power amplifier in a QFN6x6 package, covering 6 to 8 GHz. Output P1dB is 38.5 dBm CW, small signal gain 20 dB, and PAE 30% at 7 GHz.

At 32 dBm per tone the IM3 level is -24 dBc. It takes +8 V plus gate bias and draws about 5.25 A, so the board needs a solid thermal path under the package. Gain flatness is ±1.5 dB, and the surface mount format keeps wireless communication transmitters simple to build.
