The Catten line of attenuators is ranging from 1 to 20 dB signal attenuation. The models are designed in a rugged SMA housing for easy in-line connection and operation in test equipment, RF lab use and other embedded applications. The frequency of these attenuators ranges from DC to 3GHz. These units provide 1W of power dissipation (0.5W for 15dB and 20dB models) and impedance of 50 Ohms. Tolerance matching is used to provide superior temperature tracking to individual components. The attenuator’s operating temperature range is -40 to 85°C.
