Device Overview
General Description
The ATN05-0067CH is part of a family of precision GaAs MMIC fixed attenuators. The ATN05-0067CH provides a nominal 5dB attenuation over a DC-67GHz operating range. These attenuators are an ideal solution for attenuating a signal and they can be used in a wide range of applications. They are ideal for test equipment’s protection and signal overload prevention in various RF systems. A 50-ohm match is maintained over the entire operating frequency range. ATN-67CH-KIT is an evaluation kit with 5 units of each value between 0dB to 10dB.
Features
- 5dB attenuation
