立即购买 更多内容

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.
