High Performance ISM Band ASK/FSK/GFSK Transmitter IC

GENERAL DESCRIPTION The ADF7011 is a low power OOK/ASK/FSK/GFSK UHF transmitter designed for use in ISM band systems. It contains and integrated VCO and Σ-∆ fractional-N PLL. The output power, channel spacing, and output frequency are programmable with four 24-bit registers. The fractional-N PLL

高性能ISM频段ASK/FSK/GFSK发射机IC

ADF7011是一款低功耗OOK/ASK/FSK/GFSK UHF发射机，设计用于ISM频段系统，内置一个集成式VCO和Σ-Δ小数N分频PLL。输出功率、通道间隔和输出频率均可通过4个24位寄存器编程设置。利用小数N分频PLL，用户可以选择欧洲433 MHz和868 MHz频段内的任何通道频率，从而可以将ADF7011用于跳频系统。小数N分频还允许发射机在拥塞程度较低的次频段——868 MHz至870 MHz SRD频段内工作。\n\n可以从四种不同调制方案中进行选择：二进制或高斯频移键控(FSK/GFSK)、幅移键控(ASK)或开关键控(OOK)。该器件还有一个晶体补偿寄存器，它可以在输出频 • 单芯片低功耗UHF发射机\n\n• 频段：433 MHz至435 MHz \n868 MHz至 870 MHz\n\n• 片内VCO和小数N分频PLL\n\n• 可编程输出功率：\n16 dBm至+12 dBm，步进为0.3 dB;
