3 dbm inc #SCI33 fixed attenuator, N (F) marked 3.5-3.7GHz, tested see plots
attenuator made by 3dbm inc. which was founded in 1965. According to the Chicago Times, 3dbm inc was bought by Gould in 1985, but I also found an SEC filing saying that Ducomun bought 3dbm inc in 1995 (it's in their first quarter 1995 filing), and then sold it in 1998"3dbm, Inc. In August 1998, the Company sold the capital stock of its wireless communications subsidiary, 3dbm, Inc. ("3dbm"). The Company sold 3dbm because the level of investment required to ensure the long-term viability of 3dbm in the wireless system infrastructure business was more than the Company was willing to commit."I guess that is enough research to show that 3dbm is no longer with us... I ran the analyzer trace out to 20 GHz, it looks reasonable. note to me: gray cabinet, bottom drawer
