Abstract :
The operation of an RCA-1B25 neon-argon-filled glow tube as a switching element in a transmission-line network at ultra-high frequencies has been investigated. A test method has been developed and theory formulated for evaluating the behavior of the tube in terms of an equivalent susceptance and conductance. Experimental measurements have been made which show the variation of the admittance characteristics as a function of gas pressure and of the direct current.
