Patent ID: 8705652

Claim:
A pulse wireless communication device comprising: a radiation type oscillator including a three-electrode high-frequency amplifying device being integrated with a resonator to generate negative resistance, perform an oscillating operation and simultaneously function as a transmitting and receiving antenna of the pulse wireless communication device; wherein the three-electrode high-frequency amplifying device is operated based on a transmit data signal to establish a short-duration negative resistance, and a high-frequency pulse signal of an oscillating frequency/frequency band width, determined based on the negative resistance and a structure of a resonant cavity, is generated and simultaneously radiated into space; the high-frequency pulse signal radiated into space constitutes a transmitted RF signal; and the radiation type oscillator is caused to perform the oscillating operation when a received RF signal from an external wireless communication device enters the radiation type oscillator, whereby a received data signal is established based on acquisition of an IF signal owing to a mixing operation by the radiation type oscillator.
