The working frequency of the circuit can reach 100MHz, the heat loading diode limiters (D1 and D2) can transport the 10V signals to the gate circuit MC1023 without any loss. The changeable resistor R1 is the bias point that controls D1 and D2, which makes the positive voltage of D1 be -3.2v. The amplitude limiter outputs a signal that is rectified by the high speed pulse driver MC1023, and the signal is delivered to the 120MHz J-K trigger FF1 and split into two. The output of FE1 is put into the dividing 5 circuits (FF2,FF3 and FF4), then the output drive transistor Q1 of FF4 generates a square wave whose amplitude is 2~4v and frequency is 1~10MHz.
