Abstract:

Research and development was continued on a lownoise E-band amplifier. The waveguide slot was reduced to a hole only twice the helix diameter and excellent coupling was achieved through the incorporation of a probe type extension of the helix. Measurements showed negligible coupling loss, relatively smooth insertion loss vs. frequency, and total tube loss from 35-45 db over the band. Larger YIG spheres were tested in an attempt to increase the instantaneous bandwidth and reduce the filter insertion loss. Results obtained were bandwidths in the range of 143 to 224 mc with an insertion loss of 1.6 to 2.4 db across the 70-79 gc band. Initial tests were also performed on the magnetic tuning cicuit.
