Abstract

PURPOSE: To obtain a small-size keyer which can operate in a high frequency band with reduced spurious by combining the circuit which switches frequency f0 and 2f0 corresponding to the binary signal supplied to the 3-phase roller-screen electrode to the output of a pair of the single-phase roller-screen electrode.
