The ATN00-0070CSP1 is a surface-mount GaAs MMIC attenuator in a chip scale package (CSP). This attenuator is an ideal solution for attenuating a signal and can be used in a wide range of applications. The ATN00-0070CSP1 features a typical 0.3 dB attenuation with 0.1 dB attenuation flatness and 20 dB return loss across the DC to 70 GHz bandwidth. The CSP allows for extreme miniaturization of SMT footprint while providing die-level performance. GaAs MMIC technology provides consistent unit-to-unit performance in a small, low-cost form factor. A 50-ohm match is maintained over the entire operating frequency range.
