Anadigics launches high-output GaN power doubler line amplifier for 1GHz CATV

In booth 505 at the SCTE Cable-Tec Expo 2012 in Orlando, FL (17-19 October), broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is launching the ACA2428 gallium nitride (GaN) line amplifier MMIC.

Anadigics says that the GaN power doubler line amplifier uses its unique design architectures to ensure distortion-free video and audio in 1GHz CATV systems. Due to its low current consumption, the GaN line amplifier helps to save energy to enable green CATV infrastructure solutions, it is claimed.

“CATV networks are increasingly operating in a fully loaded spectrum to support high-definition television, video on demand, and high-data-rate internet,” says Tim Laverick, VP of infrastructure products. “Anadigics’ new GaN line amplifier provides a best-in-class combination of output power, linearity, bit error rate, and noise figure to ensure the highest quality of video delivery in these network conditions,” he claims. “This level of performance is coupled with exceptional efficiency and world-class reliability and ruggedness, enabling advanced green solutions that minimize power consumption and costly truck rolls.”

The ACA2428 GaN line amplifier MMIC is optimized for 50-1000MHz frequency-band applications by delivering +58dBmV output power and 21dB gain at 1GHz. Available in a 16-lead SOIC, the it is powered through the center tap of the output impedance transformer with a single +24V supply. The ACA2428 is optimized for several CATV infrastructure applications, including output power doublers for system amplifiers and deep fiber nodes.

Anadigics notes that featuires of its GaN line amplifiers include: high output power; low composite triple beat (CTB), composite second order (CSO), cross modulation, and noise figure distortion characteristics for optimal performance in a fully loaded spectrum; positive slope cable equivalent; very low bit error rate (BER); and a GaN output stage incorporated to minimize the operating (bias) current.

Samples of the ACA2428 are available now for qualified programs.
