Abstract
A 2.4 mm twin line coaxial calorimeter is the first microwave power standard in this line size to be developed at the National Physical Laboratory. The instrument will provide traceable power measurements from dc to 50 GHz and has an effective efficiency ranging from 101.1% at 1.0 GHz to 92.2% at 50.0 GHz.
