General Description

SAC3147 is a C-band GaAs MMIC power amplifier die for 6 to 8 GHz. It reaches 39 dBm CW at P1dB with 20 dB of small signal gain and 30% PAE at 7 GHz.

IM3 is -24 dBc at 33 dBm per tone. Drain bias is +8 V with a separate gate supply, at about 5.25 A, and gain holds within ±1.5 dB. The 3.7 x 4.2 x 0.1 mm die uses backside vias for epoxy attach and goes into wireless communication links such as point-to-point radio.
