技术问答

The Au6494 is a high efficiency 6W Power Amplifier suitable for application in FDD and TDD small cell base stations as well as general purpose amplification. It operates over a frequency range of 2.1GHz to 2.2GHz. 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 of less than 1μs.

The power amplifier has high gain and peak power which linearizes well in DPD systems giving better than 50dBc ACLR for 20MHz modulation bandwidth.

This amplifier uses an asymmetric Doherty architecture. The RF input does not require a DC block provided the input connection is at 0V DC. The RF output has an internal DC block.
