The balance of low 1 RF IN noise and distortion provides an outstanding solution for 2 GND drop and distribution amplifiers. 3 RF OUT/V DD Backside Paddle GND The TAT7461 is fabricated using 6-inch GaAs pHEMT technology to optimize performance and cost. On-chip negative feedback provides excellent gain and return loss stability. The TAT7461 also uses an on-chip active bias for consistent bias current and repeatable performance. Simple external tuning allows the TAT7461 to achieve excellent return loss.
