The portfolio covers frequency range up to 50 GHz and DSA with resolutions from 2-bit to 7-bit with minimum step size down to 0.25 decibels.

The DSA portfolio offers solutions for the 50 Ohm wireless market and 75 Ohm CATV and DOCSIS market with broad bandwidth and high linearity.

The main application is for system gain control for RF front modules, for cellular infrastructure, satellite and radar systems.  

This Monolithic solution integrates both the RF attenuator array and the serial or parallel digital control functions.

The DSA has a fast switching time and precise insertion loss over the attenuation and temperature range.

The DSA comes in a small QFN package or flip-chip for the 50GHz attenuator.  

Evaluations kits and PC software tools are available for concept and performance t
