Qorvo QPL9057 Flat Gain Amplifiers

Qorvo QPL9057 Flat Gain Amplifiers are designed to provide a flat 2.4dB gain over a wide bandwidth from 1.5GHz to 3.8GHz. These gain amplifiers provide 22.8dB gain, +32dBm OIP3 at a 50mA bias setting, and 0.54dB noise figure. The QPL9057 gain amplifiers require five external components to operate from a single positive supply as they are internally matched using a high-performance E-pHEMT process. The single positive supply includes an RF choke, blocking/bypass capacitors, and a bias resistor going to pin 1.

The QPL9057 gain amplifiers feature bias adjustable for linearity optimization, unconditional stability, integrated shutdown control pin, and shutdown mode pin with 1.8V logic. These gain amplifiers are housed in a green/RoHS compliant industry-standard 2mm x 2mm package. Typical applications include mobile infrastructure, repeaters, Time Division Duplex (TDD) or Frequency Division Duplex (FDD) systems, LTE/WCDMA/CDMA/GSM, and general purpose wireless.
