Device Overview
General Description
The ATN03-0040BH is a GaAs MMIC attenuator in an inline connectorized bullet housing package. The ATN03-0040BH provides a nominal 3.5 dB attenuation over a DC to 40 GHz operating range. The attenuator delivers accurate, repeatable performance with an excellent 29 dB return loss for test and measurement, and system level applications. GaAs MMIC technology provides consistent unit-to-unit performance. A 50-ohm match is maintained over the entire operating frequency range.
