Resistor Assembling Schemes for Attenuator Switches
Series Type Stepped Attenuator Scheme:
- Easy scheme, fast to assemble
- Acts like a potentiometer, easy to use
- No "Pops" or "Clicks" when switching
- Fewer parts, low costs
Shunt Type Attenuator:
- Only two resistors total in the signal chain
- Easy to build
- Lower costs than for example a ladder type attenuator
- One constant input to output resistor
- Similar behaving like a ladder attenuator but fewer parts
Simple Impedance selector switch:
- Just one resistor for each position
- Easy to build
- Not recommended for passive attenuation because of low impedances
- can be used as impedance-changer or regulator for OPA, pad or other devices which accept a fix impedance.
