Abstract

PURPOSE:To improve output impedance without using an isolator or an attenuator, by enabling the titled device to be connected directly to the output line of impedance. CONSTITUTION:A resonance circuit 20 is provided at the base (b) side of a transistor 10 whose collector is grounded and is provided with three terminal elements and it oscillates by providing an open stub 3 at the emitter (e) and generating a negative resistance. In such a case, an open stub 6 whose line length is 1/4-wave of a transmission wavelength is arranged and coupled in parallel with the open stub 3 of the emitter (e), and an output line 4 to which a resistor 7 having a value equivalent to the impedance of the open stub 6 is is connected is provided at the open stub 6, then, oscillatory output can be taken out directly from the output line 4. Thus, since the oscillatory output can be taken out directly by connecting the output line 4 without necessitating the insertion of the isolator or the attenuator, the cost of the device can be lowered, and an output level can be heightened.
