The QPA9940 from Qorvo is a Power Amplifier that operates from 2300 to 2400 MHz. It delivers an output power of 4 W with more than 32 dB of gain and has a Power Added Efficiency (PAE) of 31%. This power amplifier uses InGaP/GaAs HBT technology to provide high efficiency with an excellent DPD linearized ACPR of -50 dBc for signal bandwidths up to 100 MHz. It requires a DC supply of 5 V and consumes 406 mA of current. This amplifier is available in a surface-mount package that measures 5 x 5 mm and is ideal for use in 4G/5G small cell BTS, 5G Massive MIMO, repeaters/DAS, mobile infrastructure, and general-purpose wireless applications.
