Anadigics PAs enable Shanghai Qianjin CATV products

The firm’s GaAs based MESFETs are optimised for delivering analogue and digital video, as well as high-speed data services, over advanced hybrid fibre / coax (HFC) networks.

Shanghai Qinajin, a leading CATV infrastructure manufacturer in China, is using Anadigics’ hybrid line amplifiers in its products.

 The migration to high definition television, video on demand, and high speed internet has resulted in many CATV systems operating in a fully-loaded spectrum.  These hybrid line amplifiers have been optimised to ensure high quality video in these environments and provide outstanding ruggedness to minimise costly truck rolls.

Anadigics is shipping production volumes of its CATV hybrid line amplifiers to Shanghai Qianjin Electronics. These amplifiers are used in Shanghai Qianjin Electronics’ NOR860T-2 two-way and NOR860T-4 four-way optical receivers, which are optimised for delivering analogue and digital video, as well as high-speed data services, over advanced hybrid fibre / coax (HFC) networks.

“Working closely with Anadigics, we have developed our optical receiver products for both established and emerging CATV markets,” said Wang Guang Hai, President at Shanghai Qianjin Electronics. “We made the decision to select Anadigics as a key supplier for our optical node products due to its hybrid line amplifier performance and reliability advantages, as well as exceptional customer support.”

“We are extremely pleased that Shanghai Qianjin Electronics has selected Anadigics’ hybrid line amplifiers for its optical receiver product line,” said Michael Canonico, Vice President of Worldwide Sales at Anadigics. “Our hybrid line amplifiers lead the industry in ruggedness and reliability, helping service providers to minimise costly field repairs. We look forward to working closely with Shanghai Qianjin Electronics on the design of future CATV infrastructure products.”

A report published by Strategy Analytics, in November 2010, forecasts that hybrid amplifier blocks will show steady growth through 2014. The report details that the fastest growing CATV infrastructure segment will be amplifiers for high-definition capable networks, with a forecasted compounded average annual growth rate (CAAGR) of nearly 43% from 2009 to 2014.

“With high-definition television, video on demand, and high data rate internet, CATV systems are increasingly operating in a fully-loaded spectrum,” said Joseph Cozzarelli, Senior Director of Broadband RF Products at Anadigics. “Anadigics’ hybrid line amplifiers offer industry-leading linearity and exceptionally low noise figures to provide minimum signal degradation. This level of performance coupled with the extreme ruggedness of our hybrid line amplifiers, ensures the highest quality video delivery while minimizing costly downtime and service calls from cable plant equipment failures.”

The modules have low composite triple beat (CTB), composite second order (CSO), cross modulation, and noise figure distortion characteristics for optimal performance in a fully-loaded spectrum.

With a positive slope cable equivalent, their controlled gain limits minimise lot-to-lot variation and ensure uniformity.

They also have a high tolerance to electro static discharge (ESD) and line voltage surge for enhanced ruggedness in outdoor applications. The technology uses Anadigics’ GaAs MESFET process for a high mean-time-to-failure (MTTF).
