AD-PAARRAY3552R-SL

RF Front-end GaN Power Amplifier Biasing, Protection, and Control Reference Design

特性和优点

  • Designed to cover full Tx signal chains with integrated MCU and user-friendly GUI for faster and easier integration
  • Supports fault event protection - overvoltage (OV), overcurrent (OC), and overtemperature (OT)
  • Supports ultrafast sub-µs GaN gate voltage switching ~ (<1 µs)
  • Supports ultrafast (<10 µs) fault event protection from detection up to GaN gate pinch-off
  • Wide range of gate bias voltages from -10 V to +10 V
  • Configurable power-up and power-down sequence

产品详情

The AD-PAARRAY3552R-SL reference design provides control, protection, and proper biasing sequence for GaN power amplifier (PA) arrays. The design incorporates the AD3553R high-speed, dual-channel, 16-bit DAC to support the ultrafast sub-µs voltage settling time of GaN gates.

Key fault events, including overvoltage, overcurrent, and overtemperature, are effectively managed by the LTC7000, a static switch driver responsible for system fault protection.

The on-board MAX32666 ultralow-power ARM® Cortex®-M4 microprocessor provides essential debug and programming features for a comprehensive software development experience with the system. The system's firmware is built on ADI's open-source no-OS framework and includes a user-friendly graphical interface (GUI) for evaluation. Updates are easily applied through an SWD UART bootloader, streamlining prototyping.

The system can be powered by an external +48 V supply, requiring high current capabilities.

SCP-LT3471-EVALZ

LT3471 信号链评估板 | 双升压/反相转换器

产品详情

演示电路 SCP-LT3471-EVALZ 是双输出转换器,在升压和反相器配置中配有 LT3471EDD。两个转换器均由同一的 4.5V 至 10V 输入电源供电。升压转换器在 300mA 时的输出为 12V,而反相器在 200mA 时的输出为 –12V。

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 LT3471 的操作和配置的重要细节。有关该套件的完整说明,请参考 LT3471 数据手册。

DC1280A

LT3471EDD Demo Board | Dual 12 VOUT @ 300mA & -12 VOUT @ 200mA Boost/Inverter in 3 × 3 DFN

产品详情

Demonstration circuit 1280A is a dual output converter featuring the LT3471EDD in Boost and Inverter configurations. Both converters are powered from the same 4.5V to 10V input source. The Boost converter puts out 12V at 300mA and the Inverter -12V at 200mA. The demo circuit demonstrates small size and low component count. The LT3471 operates with inputs as high as 16V but in this demo board the input is limited by the magnitude of the Boost output. In a Boost converter the input needs to be less than the output. The DC1280A is designed so that the Inverting converter can easily be configured as a Boost. Instructions are included in the schematic. Both circuits are designed to demonstrate the soft start feature, advantages of the 1.2MHz switching frequency and the internal 42V/1.3A switches.
