For a space-charge limited double-cathode tube a theory, including transit-time effects, has been derived, which enables us to compute its impedance and its noise. If such a tube is placed in a waveguide, the elements of the equivalent microwave network of the tube can then be found by calculating the wave propagation in the guide. Measurements of impedance and noise of the tube as a function of the applied d.c. voltage were carried out at a frequency of about 3 GHz. The experimental results agree fairly well with the theory.
