2.8.7.10 External LNA Control
Depending on the system requirements, an increased sensitivity of the receiving path might be necessary. To boost the sensitivity of the receiver, an external low-noise amplifier can be used. The ATA8510/15 offers an output pin (pin 29 / RX_ACTIVE) that can be used to bias the external LNA. The activation and polarity configuration of the RX_ACTIVE pin can be done in the eepEventConf.sysEventConf.RX_ACTIVE_EN and RX_ACTIVE_POL EEPROM variables. Application-specific details can be found in External LNA Support.
