The QPA9122 is a wideband, high gain, and high peak power driver amplifier. It provides 37dB gain at 2.6GHz and achieves a peak power of 27dBm P3dB. With a quiescent current of 95mA, the amplifier can provide good DPD linearity performance with wideband signals of up to 160 MHz IBW making it perfectly suited for m-MIMO applications.
The QPA9122 is internally match 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 QPA9122 is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120 and QPA9121.
