General Description

SAC3143 is an X-band GaAs MMIC power amplifier die for 8 to 10 GHz, delivering 39 dBm CW at P1dB. Small signal gain is 21 dB (±1 dB) and PAE reaches 32% at P1dB, 9 GHz.

Two-tone IM3 is -24 dBc at 33 dBm per tone, measured at 9.35 GHz. The chip runs from +7 V with negative gate bias at about 5.25 A and measures 4.2 x 4.2 x 0.1 mm. It was built with X-band multifunction radar transmitters and point-to-point radio in mind.
