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.
- 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
The QPA9121 is housed in a 16-pin 3X3mm SMT package and is footprint and pin-compatible to QPA9120.
