Zusammenfassung:	Chaotic oscillators can generate wide-band signals and the spectrum characteristics of the signals are not changed by switching the output power of the oscillators. If communication systems could be implemented using a chaotic oscillator, the communication system need not a local oscillator, a mixer, IF amp. And so forth which are needed in conventional transceivers. Therefore the configuration of the communication system using a chaotic oscillator can be simple. The system has the characteristics of low-power consumption. In this paper we design and implement a chaotic oscillator for UWB applications. And the test results of the implemented chaotic oscillator for UWB systems are presented. The implemented chaotic oscillator has -8.11 dBm of the output power within 500 MHz channel bandwidth at 3.4 GHz of the center frequency and has about 470 MHz of -10 dB bandwidth.
