Description of the Series/Product Category
Notice: The following information refer to the series/product category as a whole. Please see the specific datasheet for specific technical information of a particular product.
The F Series RF connectors from Telegärtner are designed for use up to 3 GHZ and as such are ideally suitable for HDTV applications. The F series connectors have a threaded coupling mechanism; the impedance is controlled at 75 Ohm. Cable terminations are either crimp or solder designs. The F series connectors are primarily used in the transmission of analogue and digital video signals. With regards to return loss Telegärtner offers optimized types for professional applications, in particular for HDTV signal transmission, which feature excellent transmission performance up to 3 GHz respectively up to 4.5 GHz.
