ADRV9001 IN SINGLE-BAND 2T2R TDD TYPE SMALL-CELL APPLICATION
Figure 5. Single-Band 2T2R FDD Type Small-Cell Application
Single-Band 2T2R TDD Overview
With a minimum number of external components, the ADRV9001 transceiver can be used to build complete RF-to-bits signal chain that
can serve as RF front end in TDD type small cell type applications. ADRV9001 dual Rx and Tx signal chains enables user to implement
MIMO or diversity in their system. In TDD type applications, internal DPD block can be used to linearize external power amplifier and
improve overall system efficiency. ADRV9001 internal AGC can be used to autonomously monitor and set appropriate gain level for Rx
signal chains. For time critical TDD type applications control of the ADRV9001 TRx can be done by toggling control lines. ADRV9001
can control external Rx/Tx switch using its analog GPIOs as well as provide power amplifier bias voltage by utilizing AuxDAC outputs.
