NXP recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the PEMB1,115. The device should be placed near the antenna, and the PCB layout should minimize signal traces and vias to reduce radiation and noise.
The PEMB1,115 has an internal impedance matching network. To configure it, use the NXP-provided antenna tuning tool or follow the guidelines in the application note AN11560. The tool helps to calculate the optimal component values for the matching network based on the antenna characteristics.
The PEMB1,115 is specified to operate from -40°C to 85°C. However, it's essential to consider the temperature coefficient of the device and the antenna when designing the system, as temperature changes can affect the performance and tuning of the module.
Yes, the PEMB1,115 can be used with an external PA. However, it's crucial to ensure that the PA is designed to work with the PEMB1,115's output stage and that the overall system meets the regulatory requirements for transmit power and spectral emissions.
The PEMB1,115 supports frequency hopping through its SPI interface. The host controller can configure the device to hop between different frequencies using the frequency synthesizer control registers. NXP provides example code and application notes to help implement frequency hopping in various wireless protocols.
