Abstract
PURPOSE:To widen the frequency band with simple constitution and small size by using a double multiplication means so as to double the signal frequency and obtaining a timing clock. CONSTITUTION:An NRZ signal coming from an input terminal 1 and amplified by a preamplifier 2 is given to an FET 5. The FET 5, based on the NRZ signal, generates a harmonic wave being multiplying the frequency of the signal twice. The output of the FET 5 is given to a tank circuit 8, which extracts only the harmonic component doubled in the output of the FET 5 and gives an output. Thus, the timing clock having a double frequency of that of the NRZ signal is obtained from an output terminal 10. In this case, the FET 5 is operative up to an ultrahigh frequency and the frequency band is widened with simple constitution.
