Product Overview

The AD8339-EVALZ is an evaluation board for AD8339 device. The AD8339 is a quad I/Q demodulator configured to be driven by a low noise preamplifier with differential outputs. It is optimised for the LNA in the AD8332/AD8334/AD8335 family of VGAs. Four single-ended RF inputs can be phase aligned using the LNA inputs of an AD8334 and the 16 phase adjustment options of the AD8339. The RF input signals can be derived from three sources, user selectable by jumpers. Test points enable signal tracing at various circuit nodes. The AD8339-EVALZ requires bipolar 5V power supplies. A 3.3V on-board regulator provides power for the USB and EEPROM devices. The AD8339 is configured using the software provided on the CD included with the evaluation board, or using an external Digital pattern generator via the 20pin flat-cable connector P1.
  • Quad integrated I/Q demodulator
  • It provides 16 phase select on each output (22.5° per step)
  • Quadrature demodulation accuracy, Phase accuracy of ±1° and amplitude imbalance of ±0.05dB
  • Bandwidth for 4LO is LF to 200MHz and for RF is LF to 50MHz
  • It has output dynamic range of 160dB/Hz
  • Provides LO drive of >0dBm (50Ω), Single ended sine wave
  • Power consumption of 73mW/channel (290mW total)
  • power down can be performed via SPI (each channel and complete chip)
