Provided is a microwave-, milliwave-band, ultra-wideband (UWB) pulse wireless communication device which makes it possible to achieve a simpler structure, improved performance, smaller integration, easier design, lower power consumption, and lower cost. A radiating oscillator is constructed from a radiating oscillation substrate (S1) provided with a microwave transistor (1) which develops negative resistance in short-time operation and a resonant cavity structure. A high-frequency pulse signal having an oscillation frequency and frequency bandwidth determined on the basis of the negative resistance produced by the short-time operation of the microwave transistor (1) and the resonant cavity structure radiates into space simultaneous to being generated as a transmission RF signal. When the received RF signal arriving from an external wireless communication device is incident on a radiating oscillator, the radiating oscillator oscillates; and the received data signal is obtained on the basis of the IF signal acquired by mixing using the radiating oscillator. |
