With the E-pHEMT process, this amplifier delivers exceptional performance

RFMW announces design and sales support for the low-cost wideband, high-gain, high-linearity driver amplifier. Qorvo’s QPA9120 offers 36 dBm output 3rd order intercept (OIP3) power for pre-driver circuits used in wireless infrastructure from 1.8 to 5 GHz, including dense array, 5G m-MIMO radios. With 29 dB of gain and 22 dBm output 1dB compression (OP1dB) power, the QPA9120 is an ideal driver amplifier for a variety of applications.

 Key Features

  • Flat gain (1 dB gain flatness over 1 GHz bandwidth)
  • 50Ω I/O internal matching
  • Fast DC power shutdown
  • Single 5V supply
  • Draws only 96 mA

The QPA9120 is targeted for use as a pre-driver amplifier for wireless infrastructure where high linearity, medium RF power with efficient DC power operation are required. The device is an excellent choice for 5G dense-array m-MIMO radio applications, offered in RoHS compliant 3×3 mm QFN package.
