Transmit Antenna Diversity
Transmit antenna diversity is possible using the differential PA
and single-ended PA. The required matching network is shown
in Figure 87.
Support for External PA and LNA Control
The ADF7023-J provides independent control signals for an
external PA or LNA. If the EXT_PA_EN bit is set to 1 in the
MODE_CONTROL register (Address 0x11A), the external PA
control signal is logic high while the ADF7023-J is in the
PHY_TX state and logic low while in any other state. If the
EXT_LNA_EN bit is set to 1 in the MODE_CONTROL register
(Address 0x11A), the external LNA control signal is logic high
while the ADF7023-J is in the PHY_RX state and logic low
while in any other state.

DIFFERENTIAL PA AND
LNA MATCH
The external PA and LNA control signals can be configured
using the EXT_PA_LNA_CONFIG setting (Address 0x11B)
as described in Table 44.
