ARA05050
Reverse Amplifiers
Application:
Reverse Amplifier with Step Attenuator
Description:
The ARA05050 is a GaAs IC 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 is capable of meeting the MCNS/DOCSIS requirements for harmonic performance at a +58dBmV output level while requiring only a single polarity +5V supply.
Features:
- Low cost integrated monolithic GaAs amplifier with step attenuator
- Attenuation Range: 0-30 dB, adjustable in 2dB increments via a 4 wire parallel control
- Meets DOCSIS distortion requirements at +58 dBmV output signal level
- Low distortion and low noise
- Low signal to noise ratio at all gain levels
- Frequency range: 5-100 MHz
- 5 Volt operation
- RoHS-Compliant Packaging Option
