Additional Details:

The SKY65790-15 is designed to operate on a single positive supply voltage. The low noise amplifier is designed to minimize noise figure to improve receiver sensitivity, which is critical in LPWAN applications where signals can be very weak. The power amplifier is highly efficient to minimize power consumption, especially for battery-powered devices that need to operate for long periods. The integrated transmit/receive switch allows the antenna to be shared between the transmitter and receiver. This module is used in LoRaWAN and Sigfox gateways, base stations, and end nodes for smart cities, agriculture, and industrial IoT applications, where long range and low power consumption are critical requirements.

The device is available in a compact QFN package. It is designed to operate over a wide temperature range, making it suitable for various environmental conditions. The SKY65790-15 is designed for optimal performance in LPWAN applications.
