Abstract: PURPOSE: A circuit of generating a local signal for a wireless communication device is provided to use a Gaussian monocycle oscillator during narrowband RF and microwave communication, and to use ultrawideband properties of a pulse, thereby solving multipath fading, multipath time delay, jamming, and signal interferences. CONSTITUTION: A square wave oscillator(10) generates a square wave. A non linear transmission line unit(20) generates pulses on a rising edge and a falling edge only of the generated square wave. A differential circuit(30) differentiates generated pulse signals. An amplifier(40) amplifies outputs of the differentiated signals. The non linear transmission line unit(20) comprises as follows. One end of the first inductor(L1) is connected to a collector of a transistor(Q1). One end of the second inductor(L2) is connected to the other end of the first inductor(L1). The first varactor diode(D1) is connected between common connection points of the first and the second inductors(L1,L2) and a ground. The second varactor diode(D2) is connected between the common connection points of the first and the second inductors(L1,L2) and the other end of the second inductor(L2). A resistance(R2) is connected between common connection points of the second inductor(L2) and the second varactor diode(D2) and the ground.
