PRODUCT 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. Both the input and the output are single-ended and matched to 75 Ohms. The precision attenuator provides up to 30 dB of attenuation in 2 dB increments. The ARA05050 is offered in a 28-pin SSOP package that features a heat slug on the bottom of the package,
and is available in a RoHS-compliant option.

PRODUCT DESCRIPTION
The ANADIGICS AWM6431 WiMAX Power Amplifier is a high performance device that delivers
exceptional linearity and efficiency at high levels of output power.
Designed to operate in the upper portion of the 3.5 GHz band, it supports the IEEE 802.16-2004 and ETSI EN301-021 wireless standards.
The device requires only a single +5 V to +6 V supply and a low-current reference input.
An integrated detector can be used to monitor output power, and an integrated 20 dB step attenuator enables gain control.
No external circuits are required for biasing or RF impedance matching, thus reducing external
component costs and facilitating circuit board designs.
The AWM6431 is manufactured using advanced InGaP HBT technology that offers state-of-the-art reliability, temperature stability and ruggedness.
It is optimized for use in a 50 Ω system, and is offered in a 4.5 mm x 4.5 mm x 1.4 mm surface mount module.
