Aurasemi – RF (AU6122) (10/2023)

The AU6122 is a wideband 800mW driver amplifier suitable for application in FDD and TDD wireless infrastructure and general-purpose amplification over a wide frequency range of 1.8 to 5.0GHz. The RF input and output ports are internally matched to 50Ω for the full frequency range. This device incorporates a device enable pin with turn on/off times less than 1us. The driver amplifier has high gain and linearity and will support a high instantaneous bandwidths required for 5G NR carrier aggregated signals. The device linearizes well in DPD systems. Linearized on its own it will provide better than 50 dBc ACLR for a 20MHz 5G NR.

Features:

• Extremely Wideband – 2.3 to 4.2 GHz
