Low-Power, High-Performance, Fully Integrated
Octal Ultrasound Receiver (Octal LNA, VGA,
AAF, ADC, and CWD Beamformer)
MAX2079
General Description
The MAX2079 fully integrated octal ultrasound receiver
is optimized for high channel count, high-performance
portable and cart-based ultrasound systems. The easy-
to-use integrated receiver allows the user to achieve
high-end 2D and Doppler imaging capability using
substantially less space and power. The highly compact
low-noise amplifier (LNA), variable-gain amplifier (VGA),
anti-alias filter (AAF), analog-to-digital converter (ADC),
and digital highpass filter (HPF) achieve an ultra-low
2.8dB noise figure at RS = RIN = 200I with a very low
120mW per channel power dissipation at 50Msps. The
full receive channel has been optimized for second-
harmonic imaging with an exceptional 76dBFS SNR
over a 2MHz bandwidth, and -70dBc second-harmonic
distortion at fRF = 5MHz over the full receiver gain range.
Near-carrier dynamic range has also been optimized for
exceptional pulsed and color-flow Doppler performance
under high-clutter conditions. The bipolar front-end and
CMOS ADC achieve an exceptional near-carrier SNR of
137dBFS/Hz at 1kHz from a 5MHz tone for excellent low-
velocity Doppler sensitivity.
The device also includes an octal CWD beamformer for
a full Doppler solution. Separate mixers for each channel
are available for optimal CWD sensitivity.
The MAX2079 octal ultrasound front-end is available in a
small, 10mm x 10mm, CTBGA package and is specified
over the 0NC to +70NC temperature range.
