AN5574 Driving an external RF front-end with the BlueNRG-LP
● The BlueNRG-LP is an ultra-low-power Bluetooth Low Energy SoC device which can achieve +8 dBm of output power atantenna connector. Nevertheless, Bluetooth standards allow a maximum output power of +20 dBm (local regulations can stilllimit the output power to a lower value).
● Especially for this reason, the BlueNRG-LP gives the possibility to control an external RF front-end, that can increase the outputpower by using the integrated power amplifier.
● In addition to a power amplifier (PA), RF front-ends can usually integrate a low noise amplifier (to improve sensitivity), TX/RXswitching circuitry, matching network and harmonic filters.
