control pins DIG1/DIG2, the RF signal is amplified by an optional low-noise amplifier (N2) and
fed to the radio transceiver using the second RX/TX switch (SW1).
During transmit the AT86RF231 TX signal is amplified using an external PA (N1) and fed to the
antennas via an RF switch (SW2). In this example RF switch SW2 further supports Antenna
Diversity controlled by the differential pin pair DIG1/DIG2.
The security engine (AES) and High Data Rate Modes do not require specific circuitry to oper-
ate. The security engine (AES) has to be configured in advance, for details refer to
Section 11.1
“Security Module (AES)” on page
128. The High Data Rate Modes are enabled by register bits
OQPSK_DATA_RATE (register 0x0C, TRX_CTRL_2), for details refer to
Section 11.3 “High
Data Rate Modes” on page
137.
