PLUGIN catalogue 2018

Coaxial - general data 24 he demands placed on space communications systems are continuously increasing while the challenge is to maintain their extreme reliability and versatility, in order to accommodate the long system lifetimes of all missions. If it is a sector in space technologies that is developing extremely rapidly, it is certainly this one. In the same way as for our entire range, Plug In o ers you the widest choice of hermetic feed- throughs covering the frequency ranges currently used in missions and which have to undergo long time thermalvacuum tests. In the following pages you will nd a detailed description of each type of hermetic feed- through according to the frequency and wavelength range used by your system. The table below shows you the bands, depending on the di e- rent technical applications. Designation Frequency range Wavelength range Typical uses L band 1 to 2 GHz 15 cm to 30 cm Military telemetry, GPS, mobile phones (GSM), amateur radio S band 2 to 4 GHz 7.5 cm to 15 cm Weather radar, surface ship radar, and some communications satellites (microwave ovens, microwave devices/communications, radio astronomy, mobile phones, wireless LAN, Bluetooth, ZigBee, GPS, amateur radio) C band 4 to 8 GHz 3.75 cm to 7.5 cm Long-distance radio telecommunications X band 8 to 12 GHz 25 mm to 37.5 mm Satellite communications, radar, terrestrial broadband, space communications, amateur radio, molecular rotational spectroscopy Ku band 12 to 18 GHz 16.7 mm to 25 mm Satellite communications, molecular rotational spectroscopy K band 18 to 26.5 GHz 11.3 mm to 16.7 mm Radar, satellite communications, astronomical observations, automotive radar, molecular rotational spectroscopy Ka band 26.5 to 40 GHz 5.0 mm to 11.3 mm Satellite communications, molecular rotational spectroscopy Q band 33 to 50 GHz 6.0 mm to 9.0 mm Satellite communications, terrestrial microwave communications, radio astronomy, automotive radar, molecular rotational spectroscopy V band 50 to 75 GHz 4.0 mm to 6.0 mm Millimeter wave radar research, molecular rotational spectroscopy and other kinds of scienti c research Wband 75 to 110 GHz 2.7 mm to 4.0 mm Satellite communications, millimeter-wave radar research, military radar targeting and tracking applications, and some non-military applications, automotive radar F band 90 to 140 GHz 2.1 mm to 3.3 mm SHF transmissions: Radio astronomy, microwave devices/communications, wireless LAN, most modern radars, communications satellites, satellite television broadcasting, DBS, amateur radio D band 110 to 170 GHz 1.8 mm to 2.7 mm EHF transmissions: Radio astronomy, high-frequency microwave radio relay, microwave remote sensing, amateur radio, directed-energy weapon, millimeter wave scanner
