SX1272屬于開發(fā)板套件編程器的射頻評(píng)估開發(fā)套件開發(fā)板。由Semtech Corporation制造生產(chǎn)的SX1272射頻評(píng)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(shí)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(diǎn)產(chǎn)品范圍從射頻信號(hào)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(diǎn)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(dú)提供的特定射頻產(chǎn)品或系列。

GENERAL DESCRIPTION

Semtech’s SX1272/73 family provides ultra long range while maintaining low current consumption, making it optimal for numerous applications.

With Semtech’s patented modulation technique the device can achieve sensitivity of over -138.5 dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20 dBm power amplifier creates the highest link budget making it optimal for any application requiring range. This modulation technique also provides significant advantages in blocking and selectivity over FSK.
