Allen Industries 50V60-001 rotary step attenuator 0-60dB SMA Tested
If you look at the plots, one set for each of the two units, you can se that indeed they are good 2 GHz. One switch (with the black label) has a rotary switch at its back, the one with the blue label does not have this switch – I’m treating them as identical, so if you order one, you will get one.
