The differential phase shifter is an interesting four-port passive microwave network composed of two separate lines, the main line and the reference line, and providing stable phase difference between the two output signals over the specified bandwid

A 45 degree differential microstrip phase shifter operating in the frequency band ranging from 1.4 GHz to 2.7 GHz is presented in this paper. It is designed by adopting the model of double parallel Schiffman phase shifter and simulated on an FR4 subs

Two peptides were synthetised by coupling 3-hydroxy propionic acid with L-ornithine and 3-hydroxy-DL-ornithine, to be tested later in order to establish whether they are links in the biosynthesis of clavulanic acid.
