RF Power Amplifier
The SiFLEX02 module contains a discrete high performance RF Front End for low-power and low-
voltage 900MHz wireless applications. It is capable of 250mW output power, providing miles of range
in outdoor applications.
The signals DIG3 and DIG4 from the RF212 radio are used for transmit enable (TXEN) and receive
enable (RXEN) respectively. When transmitting the DIG3 signal will be high and DIG4 will be low,
which is controlled by the RF212. When receiving DIG3 will be low and DIG4 is high. In order to
configure this functionality, the PA_EXT_EN bit in register TRX_CTRL_1 (0x04) of the RF212 needs to
be set as a one. In addition the bits PA_LT[1] and PA_LT[0] in register RF_CTRL_0 (0x16) should both
be set to one to maximize the PA lead time to 8usec.
When putting the module to sleep the PA_EXT_EN bit should be set as zero. Upon wakeup the
PA_EXT_EN should be set back to one.
