摘要： An oscillator body 10 defines a waveguide 11 in which is supported a Gunn diode 15. The Gunn diode 15 is thermally and electrically connected to a surface of a heat sink having a cylindrical main body 40 which is supported in the body 10 by an interference or tight sliding fit. A frequency tuning probe 65 is supported by an interference fit for longitudinal displacement into the region between a lower face 66 of an RF choke 13, in order to allow the frequency of operation of the oscillator to be controllably adjusted. A cylindrical short circuit 62 is supported in a cylindrical portion 61 of the waveguide 11 by an interference fit, whereby the output power of the oscillator can be accurately and reliably adjusted. A rectangular cross-section portion of the waveguide 11 meets the cylindrical portion 61 with a step transition.

摘要： A wireless communication device having extremely simple constitution is used, and a low-cost and low power consumption wireless network system with high-quality signals is provided. The wireless network system comprises a plurality of wireless communication devices (101) each comprising a radiating oscillator (1) configured to integrate a transistor into a microwave oscillating resonator to generate a negative resistance and to commonly use a function of an antenna (11), an intermediate frequency signal generating section (4) and a receiving signal detecting section (7). In the wireless network system, the wireless communication devices are arranged to face at a position, at least one of the wireless communication devices has an intermediate frequency signal generating section having a frequency band signal generating function different from that of others, the receiving signal detection section having a function that can discriminate and receive a frequency band different from that of others, a signal transmitted from the one wireless communication device is transmitted to the other facing wireless communication device, and the other facing wireless communication device receives and extracts the signal by the receiving signal detecting section.

摘要： The invention relates to a vehicle radar system having an oscillator (5) which generates a high frequency signal, in time segments only and in accordance with a control signal, during functioning of the radar system. Said oscillator comprises a microwave diode, in particular a Gunn or impatt diode, accommodated inside a casing-like body. In accordance with the invention, at least one of the following elements: ohmic resistance, transistor or IC body, is so arranged as to be thermally bonded with the casing-like body or an element thermally connected thereto. Said component fulfils at least one other function beyond that of generating heat inside the radar system circuit. This guarantees that the oscillator begins to oscillate in sure and reliable manner, even at very low temperatures, and in particular in pulsed operating mode.
