Abstract(in English) | An NRD guide pulse radar front-end was fabricated for level sensor applications at 60GHz. Main emphasis was placed on circuit configuration. Typically, an oscillation power is divided by a junction circuit and is introduced into two parts. One is for transmitting wave, and the other is for LO wave to construct hetero-dyne detection. And the frequency of the former is up-converted so as to be different from the frequency of the LO wave, and thus, an amplifier is installed in the transmitting side due to low power of the up-converted millimeter-wave. In this paper, we proposed a new circuit configuration, which consists of a Gunn oscillator with two output ports to eliminate a junction circuit, a direct pulse-modulator to obtain a high level transmitting power without an expensive millimeter-wave amplifier, and a filter-based down-converter with an up-converter as a local oscillator. A maximum sensing distance was found to be 120m, while that was estimated to be 42m in the typical pulse radar without an amplifier, and thus the high performance of the proposed radar was confirmed. |
