ARA2004中文资料Reverse Amplifier with Step Attenuator数据手册Skyworks规格书

描述 Description

Please note: this product is being discontinued and is not recommended for new designs.

The ARA2004 is designed to provide the reverse path amplification and output level control functions in a CATV Set-Top Box or Cable Modem. It incorporates a digitally controlled precision step attenuator that is preceded by an ultra low noise amplifier stage, and followed by an ultra-linear output driver amplifier. This device uses a balanced circuit design that exceeds the MCNS/DOCSIS requirement for harmonic performance at a +60dBmV output level while only requiring a single polarity +5V supply.
