QPA9121 Datasheet 0.5w Driver Amplifier

Manufacturer: Qorvo

Overview: QPA9121 ® High Gain, 0.5 W Driver Amplifier Product Overview The QPA9121 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 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 amplifier has been proven to provide excellent DPD correction with 5G signals as wide as 160MHz. The QPA9121 is housed in a 16-pin 3X3mm SMT package and is footprint and pin-patible to QPA9120.
