The SoC’s low power consumption provides solutions in wireless infrastructure, repeaters and distributed antenna systems

The QPA9121 from the U.S-based semiconductor company Qorvo, is a wideband, high gain, and high peak power driver amplifier. With Qorvo’s GaAs HBT process, this amplifier provides 27dBm P3dB with 28dB gain at 2.6GHz. With a quiescent current of 95mA the part is well suited as a driver in a Tx path DPD loop, for m-MIMO applications.

The QPA9121 is internally matched to 50Ω over the entire operating frequency band of 2.3-5.0 GHz and incorporates a shut-down function through the VPD pin. The amplifier has been proven to provide excellent DPD correction with 5G signals as wide as 160MHz.

Features

  • ½ Watt of RF power from 2300 to 5000 MHz
  • Draws only 95 mA
  • 5 V power supply
  • OIP3 is 32 dBm
  • DC power shutdown feature
