    If the dongle is used in the presence of very strong signals, such as Wi-Fi, then there will be a performance improvement by switching off the Low-Noise Amplifier (LNA) in the front-end to stop the input stage of the JN5148 device from being overloaded with other signals. The LNA can be bypassed using DIO1 - driving DIO1 low will bypass the LNA.
