RF Step Attenuator

RF STEP ATTENUATOR

The schematic diagram of the step attenuator is designed for a nominal impedance of 52 ohms. Resistance values are in ohms. Resistors are 1/4 watt, carbon composition types, 5% tolerance. You must drill a hole through each partition wall to route bus wire. Keep all leads as short as possible. The attenuator is bilateral which means the input and the output ends may be reversed if you would like. Sheilding partitions between sections is necessary to reduce signal leakage.._{From ARRL Antenna Book 1994 p27-37}
