## Abstract Optimization of constant amplitude broadband inversion pulses for maximum inversion over a range of multiple fields yields more regular pulses with better tolerance to __B__~1~ errors than those optimized for a single field. These multiβfrequency improved constant amplitude (MICA) pulse

Recently we developed an efficient broadband decoupling sequence called SPARC-16 for liquid crystals [J. Magn. Reson. 130, 317 (1998)]. The sequence is based upon a 16-step phase cycling of the 2-step TPPM decoupling method for solids [J. Chem. Phys. 103, 6951 (1995)]. Since then, we have found that
## Abstract A method for improving broadband phase performance of commonβsource/commonβgate (CS/CG) active balun is presented. By setting different terminal impedances and DC bias, the phase error of the balun can be controlled within 7Β° from 1 to 20 GHz in simulation. A fabricated 2β40 GHz balance
