Abstract :
A double-slab ferrite field displacement isolator has been constructed for the 10.7-11.7 kmc band with the following performance: reverse loss of 70 db from 10.8-11.7 kmc and 64 db at 10.7 kmc; forward loss less than 1 db, except 1-1.2 db between 11.6 and 11.7 kmc; vswr less than 1.15, except 1.15-1.20 between 11.6 and 11.7 kmc; variation in forward loss less than 0.1 db for any 20 mc channel.
