  • Allows for compact system design and requires very few external components for operation
  • Suitable for small cell base station applications

The QPA9418 by Qorvo is a high-linearity two-stage power amplifier in a low-cost surface-mount package with on-chip bias control and temperature control circuits, suitable for small cell base station applications.

The QPA9418 provides 30.6 dB gain and +27 dBm linear power over the 1805 – 1930 MHz frequency range. This amplifier is able to achieve −48 dBc ACLR at +27 dBm output power using 20 MHz LTE signal and offers high linearity of -50 dBc ACPR.

The QPA9418 integrates two high-performance amplifier stages onto a module to allow for compact system design and requires very few external components for operation while drawing 420 mA of current from a 4.5 volt supply. The amplifier is bias adjustable, thus allowing the amplifier’s power consumption to be optimised. The QPA9418 is available in a 7 x 7 mm surface-mount package.
