Abstract

1,091,777. Radio transmitting apparatus. DANFOSS A.S. March 2, 1965 [March 3, 1964], No. 8974/65. Heading H4L. A transmitter is provided with a protective device for the power output valve, consisting of a junctionless, non-rectifying solid-state switching device connected across the input to the modulator which changes from a highresistance to a low-resistance condition when the input signal voltage exceeds a threshold value and reverts to its original condition when the current flowing through it falls below a predetermined value.
