Low Cost Amplifier Meets Performance and Reliability

Requirements for DOCSIS Two-Way Cable Systems

ANADIGICS (Nasdaq: ANAD), a leading supplier of wireless and broadband communications solutions, has introduced the ARA2005, a new GaAs (gallium arsenide) CATV reverse amplifier that provides the reverse path amplification and output level control functions necessary in various two-way CATV system designs.

The ARA2005 has been developed for high-speed cable modems, telephony over cable systems and open cable set-top boxes and meets the reliability and performance requirements of fiber nodes, mini nodes and CMTS (Cable Modem Termination Systems).

"There is a high level of customer interest and acceptance for the ARA2005 and we have received very strong feedback from the many cable equipment manufacturers who are currently evaluating our solution," said Ron Michels, Vice President of Cable and Broadcast Products at ANADIGICS, Inc. "This new CATV reverse amplifier makes it possible for customers to accelerate and simplify their designs, while reducing manufacturing complexity and cost. As a result, we have already received cable modem and set-top box design-ins. I expect that we will participate in DOCSIS 1.1 certification for at least one of these platforms in the second half of this year."

Designed for compatibility, the ARA2005 capitalizes on existing functionality in most DOCSIS cable modem baseband IC solutions, reducing the complexity of the return path amplifier and resulting in a simplified package design and smaller die. When coupled with ANADIGICS' 6-inch GaAs wafer manufacturing capability, the ARA2005 offers a low cost return path amplifier solution. Patent-pending protection circuitry, originally developed for ANADIGICS' infrastructure amplifier products, was incorporated to provide the rugged ARA2005 with the high reliability necessary for the harsh CATV environment.

The ARA2005 is designed with a digitally controlled precision step attenuator to control gain in the reverse path. Its design is preceded by an ultra low noise amplifier stage, and followed by an ultra-linear output drive amplifier. This results in a balanced design that meets or exceeds the MCNS/DOCSIS requirement for harmonic performance at +60 dBmV output levels while only requiring a single polarity +5V supply. Operating in a 5-100 MHz frequency range with a typical noise figure of 3 dB, the ARA2005 demonstrates a typical second harmonic distortion level of -75 dBc and third harmonic distortion level of -60 dBc. Both the input and output are matched to 75 ohms. In addition, The step attenuator varies gain in 4 dB steps over a range of 58 dB by means of a 4-bit power control interface.

According to Michels, the importance of the step attenuator is reflected with each application. As an example in set-top boxes and cable modems designs, it is used as a power amplifier where varying the gain allows the system to vary the output power from the set-top box. This is essential as the amount of loss between the box and the receiver (node) varies from house to house.

The ARA2005 reverse amplifier is housed in a 28-pin SSOP, and is priced at $2.85 in quantities of 10,000. Samples of the device are available. It is manufactured at the Company's state-of-the-art facility in New Jersey and is 100% RF tested before shipping.
