Note : Your request will be directed to pSemi.

The PE43508 from pSemi is a 6-bit, 50-ohm Digital Step Attenuator that operates from 9 kHz to 50 GHz. It has a 31.5 dB attenuation range in 0.5 dB and 1 dB steps, and it is capable of maintaining 0.5 dB and 1 dB monotonicity through its 50 GHz bandwidth. This high-performance DSA features low insertion loss, fast switching time and low attenuation error. The PE43508 also delivers glitch-safe attenuation state transitions, which eliminates the positive glitch. 

The DSA is available as a flip-chip, monolithic die, and is ideal for mmWave applications including 5G test and measurement, 5G wireless infrastructure, point-to-point communication systems and very small aperture terminals (VSAT).
