SX1257屬于開發(fā)板套件編程器的射頻評估開發(fā)套件開發(fā)板。由Semtech Corporation制造生產(chǎn)的SX1257射頻評估和開發(fā)套件，開發(fā)板本系列中的產(chǎn)品適用于在已知實施環(huán)境中，提供能訪問射頻相關(guān)器件的功能或者有助于訪問該功能。所含的焦點產(chǎn)品范圍從射頻信號鏈元器件（如放大器和檢測器）到模塊化收發(fā)器，以及不直接包含焦點產(chǎn)品的適配器硬件，但此類硬件可供方便地訪問用戶單獨提供的特定射頻產(chǎn)品或系列。

GENERAL DESCRIPTION

The SX1257 is a highly integrated RF front-end to digital I and Q modulator/demodulator Multi-PHY mode transceiver capable of supporting multiple constant and non-constant envelope modulation schemes. It is designed to operate over the 862 - 960 MHz European, North American and Japanese ISM (Industrial, Scientific and Medical) license exempt frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set.
