ADRV9001 EXAMPLE USE CASES

The section provides an overall idea on how an ADRV9001 integrated transceiver can operate as an RF front end in different applications. The
list is not exhaustive, and there are other applications the ADRV9001 can serve.
Each example is accompanied with a table that explains the main limitations and highlights when implementing the ADRV9001 in the end
application.

ADRV9001 IN A SINGLE-BAND 2T2R FDD TYPE SMALL-CELL APPLICATION

Single-Band 2T2R FDD Overview
With a minimum number of external components, the ADRV9001 transceiver can be used to build complete RF-to-bits signal chains that
can serve as the RF front end in small-cell type applications. The ADRV9001 dual receiver and transmitter signal chains allow to implement
multiple-input multiple-output (MIMO) or diversity in the system. The ADRV9001 internal AGC can be used to autonomously monitor and set
appropriate gain levels for the receiver signal chains. For non-time critical FDD type applications, the ADRV9001 transceiver can be controlled
through application programming interface (API) commands that use the serial peripheral interface (SPI).

Functionality Constraints and Limitations
Receiver Signal Path Ensure an appropriate level of isolation between Rx1 and Rx2 as well as receiver to transmitter at the system level. In the example, the RxB inputs
are used only during initialization calibrations.
