RF & Microwave Passive Components
SHF Communication Technologies AG
SHF’s microwave components are broadband devices suitable up to 110 GHz. Our SHF BIAS TEES are well known but perhaps a slight variation does suit your application even better. DIPLEXERS are bias tees with a certain bandwidth in the low frequency path to combine or separate high frequency and low frequency signals into or out of a single line. DC-FEEDERS are bias tees without the capacitor. Therefore, it provides slightly lower insertion loss in case it is connected to an AC-coupled device which already has a capacitor on its input. Based on our air line construction, these passive components provide resonance-free transmission over the entire operating range.

Solar Radiation (Sunshine) Test
This test determines the effects of direct solar radiation on components and material. The heating effects of solar radiation differ from those of high air temperature in that the amount of heat absorbed depends on the roughness and color of the surface on which the radiation is incident and the angle of incidence to the sun. Variations in the intensity of solar radiation over the surface of the component, may cause components to expand or contract at different rates, which can lead to severe st...show more -
