General Description

SAC3146 is a 2 to 6 GHz GaAs MMIC power amplifier die that puts out 33 dBm CW at P1dB. Small signal gain is 19 dB with ±2 dB flatness, and PAE is 27% at 4 GHz.

For two-tone work, IM3 is -23 dBc at 28 dBm per tone. Supply is +8 V on the drain plus a negative gate, with roughly 1200 mA drawn. The 2.93 x 2.5 x 0.1 mm chip has a metallized back for grounding and is aimed at S and C band multifunction radar and point-to-point radios.
