The L- and S-band double-balanced converters are being manufactured. The C-band double-balanced converter was improved regarding Ka-band signal leakage into the C-band port more work is being done in this respect. Average conversion loss is about 12 db. The X-band double-balanced converter was improved regarding X-band matching which presently meets the VSWR specification in the frequency band from 7 to 10.1 Gc but does not meet specifications in the frequency band 10.1 to 11.0 Gc. Effort to improve the match is continuing. Ten Sylvania D5354 diodes were received and tested individually and in a complete converter. Results are according to the specifications. The conversion loss is below 8 db for the individual diodes and below 10 db for the converter tests. The impedance characteristics do not differ significantly from those of the earlier D5253 diodes.
