General Description

SAC3952 is a balanced GaAs MMIC driver amplifier die covering 26 to 45 GHz. Output P1dB is 27 dBm with 15 dB of small signal gain, ±1.5 dB gain flatness and an 8 dB noise figure.

Thanks to the balanced topology, input and output VSWR stay at 1.35:1, so cascading it with filters or mixers is less touchy. Bias is +5 V at 800 mA plus a negative gate voltage, and the fully passivated die measures 2.6 x 2.5 x 0.1 mm. It targets Ka-band point to point radio, SATCOM and test equipment.
