Abstract :
Coaxial resistors with a calculable frequency dependence have been realized at PTB as a part of the chain from the DC quantized Hall resistance to the capacitance standard. The construction of resistors with nominal value of 1000 Omega and 1290.64 Omega is described. A modified construction of the original Haddad resistor allows a full dismantling while the outer shielding is intact, and the resistance is adjustable within 10-10-6.
