AMRG Trans + Vishay SMD (standard)
Vishay Z-foil + Takman REX

A shunt stepped attenuator is a simple design where the signal is fed through a fixed series resistor (Rin) and the shunt resistor (Rg), is selected from 48 values ranging from zero to infinity by means of a selector switch. Although a shunt design presents a variable input impedance to the signal source, this has little effect in practice and the benefits of a single resistor and switch in the signal path far outweigh any potential matching issues.
