Ultrasound transceiver saves space, power
The shift of medical ultrasound equipment from hospitals to smaller clinics means the equipment has to be smaller, more portable and less expensive without any loss in performance. Maxim Integrated’s octal ultrasound transceiver will says the company save 40% board space and consumes 30% less power than conventional architecture.
The MAX2082 integrates 8 channels of 3-level 200V pulsers and T/R switches, an octal ADC, octal LNA, and octal VGA, CW mixers, anti-aliasing filters, and coupling capacitors into a small package requiring less than 10 sq in.
Traditional designs include over nine components in the T/R switch alone for each of up to 128 channels, so the transceiver displaces thousands of discrete parts. Power-supply noise and switching noise are all minimised for superior image quality.
The higher image quality and performance is enabled byimproved system sensitivity and image quality through an ultra-low noise figure (2.8 dB at RIN = RS =200O) and a highdynamic-range receiver (76 dBFS SNR at fIN = 5MHz and 2MHz bandwidth)>
The new transceiver is available in a 10 mm x 26 mm BGA package and specified over the 0°C to +70°C temperature range.
