Two different board layouts are available for the ADF7023. In the first layout there are separate matching circuits for both the single ended PA and for the differential LNA/PA. This layout is used on the EVAL-ADF7023DB1 and EVAL-ADF7023DB3 evaluation boards.
In the second layout there is a single matching network connecting the single ended PA and the differential LNA/PA. This layout is used on the EVAL-ADF7023DB2 and EVAL-ADF7023DB4 evaluation boards.
Both layouts are 4-layer boards and use 0402 passives.
