Quadrature Hybrid
Model NMQH-002

Features:

NMQH-002
NMQH-002 Quadrature Hybrid

  • Non-Magnetic, Low Eddy Current Design
  • Available from 10-450Mhz
  • Ultra-low Insertion loss <0.2db with excellent amplitude and phase balance
  • Available in both 2.5kW and 12kW versions


Description:

These quality quadrature hybrids are specially designed for high-power NMR. They are completely non-magnetic and can be used inside a magnet bore at field strengths of up to 12T. Careful layout and a non-metallic case minimize eddy currents making these parts fully compatible with high performance gradient sets and EPI imaging. Available in a wide range of center frequencies from 10-450 MHz, both high power and ultra-high power versions are available. Combined low insertion loss (,0.2db typical), excellent channel balance (<0.2db typical), and well matched phase characteristics (90+/-3 degrees) mazimize power efficiency and signal to noise ratio of high performance coil designs.
