Abstract
To provide a microwave/milliwave UWB pulse wireless communication device that enables realization of structural simplification, high performance, compact integration, easy design, low power consumption, and low cost. A radiation type oscillator is configured by a radiation type oscillator substrate Sequipped with a microwave transistorfor generating negative resistance by short-duration operation and a resonant cavity structure, a high-frequency pulse signal of an oscillation frequency/frequency bandwidth determined based on negative resistance produced by the short-duration operation of the microwave transistorand the resonant cavity structure is generated as a transmitted RF signal and simultaneously radiated into space, and the radiation type oscillator is caused to perform oscillating operation when a received RF signal arriving 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 mixing by the radiation type oscillator itself.
