Abstract
A 50-ohm digital step attenuator has been developed having 0.2-dB resolution and 51-dB maximum loss. This device has been tested from dc to 10 MHz, where a +5-degree maximum differential phase shift was measured. Preliminary tests indicate that the attenuator may operate satisfactorily at frequencies as high as 100 MHz. No signal discontinuity occurs during switching, and positive confirmation of step activation is provided. The attenuator is constructed on a 14.5 by 3.2-cm (5.7 by 1.25-in.) double-sided etched circuit card, and occupies a volume of less than 74 cms (4.5 in.*).
