Product Overview

The AD9279-65EBZ is an evaluation board for AD9279 octal LNA/VGA/AAF/ADC AND CW I/Q demodulator device. It contains eight channels of a variable gain amplifier (VGA) with a low noise preamplifier (LNA), an anti-aliasing filter (AAF), an analog to digital converter (ADC), and an I/Q demodulator with programmable phase rotation. Each channel features a variable gain range of 45dB, a fully differential signal path, an active input preamplifier termination, and a maximum gain of up to 52dB. The channel is optimized for high dynamic performance and low power in applications where a small package size is critical. The LNA has a single ended to differential gain that is selectable through the SPI. Assuming a 15MHz noise bandwidth (NBW) and a 21.3dB LNA gain, the LNA input SNR is roughly 94dB. In CW doppler mode, each LNA output drives an I/Q demodulator that has independently programmable phase rotation with 16 phase settings.
  • It has 8 channels of LNA, VGA, AAF, ADC, and I/Q demodulator
  • It provides low power of 141mW per channel, TGC mode, 40MSPS
  • Its TGC channel input referred noise of 0.8nV/√Hz, max gain
  • It has flexible power down modes
  • It provides fast recovery from low power standby mode of <2 μs
  • It has input referred noise of 0.75nV/√Hz, and gain of 21.3dB
  • It has programmable gain of 15.6dB/17.9dB/21.3dB
  • It has 0.1dB compression of 1000mV p-p/750mV p-p/450mV p-p
  • It has dual mode active input impedance matching
  • It has attenuator range of −45dB to 0dB
