Relay attenuator

WebAug 4, 2014 · \$\begingroup\$ @SpehroPefhany Relays are probably the best solution to this problem at this point. But unfortunately the path that the signal has to go through is potentially quite long. For a 4 bit stepped attenuator with 16 steps, the signal might have to travel from board to relay and back as many as 8 times (16 junctions). And relays are ... http://vaneijndhoven.net/jos/switchr/design.html
