AD-PAARRAY3552R-SL

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

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.

EVAL-AD5676RARDZ

Evaluation Board for the AD5676R WLCSP

立即购买 更多内容

特性和优点

  • Full featured evaluation board for the AD5676R WLCSP
  • On-board or external power supply
  • On-board or external voltage reference
  • Arduino® Uno form-factor, mates with SDP-K1
  • PC control via Analysis | Control | Evaluation (ACE) Software

产品详情

The EVAL-AD5676RARDZ allows users to quickly prototype AD5676R circuits and reduce design time. The AD5676R operates from a single 2.7 V to 5.5 V supply. The AD5676R incorporates an internal 2.5 V reference to give a full-scale output voltage of 2.5 V or 5 V. An ADR4525 is also provided on-board as a 2.5V reference source. A different external reference voltage can be applied via the EXT_REF SMB connector or test pin if needed.

The EVAL-AD5676RARDZ interfaces to the USB port of a PC via a system demonstration platform board (SDP-K1 ). The Analysis | Control | Evaluation (ACE) software is available for download from the EVAL-AD5676RARDZ product page to use with the evaluation board to allow the user to program the AD5676R. A peripheral module interface (PMOD) connection is also available to allow the connection of microcontrollers to the evaluation board without the SDP-K1 board. When a microcontroller is used through the PMOD connection, the SDP-K1 board must be disconnected, and the user is unable to operate the ACE software.

The EVAL-AD5676RARDZ is compatible with the EVAL-SDP-CK1Z (SDP-K1), which should be purchased separately. A typical connection between the EVAL-AD5676RARDZ and the SDP-B controller board is shown in the user guide. For full details, see the AD5676R data sheet, which must be used in conjunction with the user guide when using the EVAL-AD5676RARDZ.
