- Models with center frequencies from 25-400MHz available
Description:
These ultra-high quality integretated TR switch/ preamplfier units allow extremely low
total noise figure, high power handling, and very low i nsertion loss. A unique low voltage
design allows high performance without endagering subjects or operator personel. Designed
for linear coil use, a pair can be used with two quadrature hybrids for quadrature coils resulting
in substatial improvements in total system noise figure.
Like many Nova Medical products, this switch can be provided for fast switching speeds or
without the integrated preamplifier.
