Analog Devices Inc. EVAL-ADRF6521 Evaluation Board
Analog Devices Inc. EVAL-ADRF6521 Evaluation Board is designed to quickly and easily demonstrate the ADRF6521 Dual-Channel Variable Gain Amplifier (VGA) in a single-ended and differential configuration. The high spurious-free dynamic range over the gain range makes the ADRF6521 VGAs ideal for communication systems with dense constellations, multiple carriers, and nearby interferers.
The ADI EVAL-ADRF6521 Evaluation Board allows the user to test all the functions and features offered by the ADRF6521, including analog gain control, output common-mode control, and output DC offset control. The EVAL-ADRF6521 Evaluation Board signal path traces are matched and are intuitively laid out on the four corners, providing easy interfacing with other evaluation boards.
