SCP-LT3045-1-EVALZ

LT3045-1 信号链评估板| 500mA 超低噪声正 LDO

产品详情

演示电路 SCP-LT3045-1-EVALZ 是 20V、500mA 低压降(LDO)稳压器,设计用于噪声敏感电路中同类较佳的低噪声操作。它易于配置用于较宽的输出范围,并具有高 PSRR,操作极为安静。

像信号链电源系列中的所有电路板一样,该板可轻松插入其他 SCP 板中,以形成完整的信号链电源系统,从而能够快速评估低功耗信号链。要评估该评估板,需要一些通用的 SCP 硬件,即:

  • SCP-INPUT-EVALZ
  • SCP-OUTPUT-EVALZ
  • SCP-1X5BKOUT-EVALZ
  • SCP-THRUBRD-EVALZ
  • SCP-FILTER-EVALZ
  • SCP-1X2BKOUT-EVALZ
  • SCP-5X1-EVALZ

 

为了正确评估 SCP 系列演示板,您将需要 SCP Configurator 配套软件。SCP Configurator 可以帮助您为您的设计选择正确的电路板和拓扑。

请注意,演示手册并未涵盖关于 LT3045-1 的操作和配置的重要细节。有关该套件的完整说明,请参考 LT3045-1 数据手册。

DC2491A

LT3045演示板|20V、500mA、超低噪声、超高PSRR RF LDO稳压器

产品详情

演示电路DC2491A内置LT3045EDD,这是一款具有可编程限流功能的500mA、超低噪声和超高电源电压抑制比(PSRR)低压差(LDO)稳压器。DC2491A的输入电压范围为3.8V20VLT3045提供500mA的最大输出电流,但在此电流水平下,热性能将最大输入电压限制在8.3V,无需较大的覆铜面积或强制空气冷却。

除具有超低噪声和超高PSRR特性外,该稳压器还提供可编程电源良好功能以及可编程限流功能。通过检测ILIM引脚电压也可实现电流监控。

产品详情

The AD-JUPITER-EBZ is a versatile software-defined platform based on Analog Devices ADRV9002 and Xilinx Zynq UltraScale+ MPSoC. The ADRV9002 is a new generation RF transceiver that has dual-channel transmitters, dual-channel receivers covering a frequency range of 30 MHz to 6 GHz. This device has a high-quality RF linearity performance and a set of advanced features like fast profiles switching, flexible power vs. performance configuration, fast frequency hopping, multi-chip synchronization, and digital pre-distortion (DPD) for narrow and wide band waveform.

The evaluation platform includes XCZU3EG processing device that has a wide range of interfaces, making the system capable of local processing or streaming to a remote host. It comes integrated in a self-contained ruggedized aluminum case, which gives flexibility in evaluating and prototyping across different environments.
