Abstract :
Two bridge circuits for impedance measurement at very-high frequency are described. The first is a hybrid junction tunable over the 100 to 500-Mc range, and capable of great sensitivity. The second is an untuned Wheatstone type for service over the same frequency range. Design features and sample performance characteristics are given for both units.
