Anadigics announces GaN amp for 1.2 GHz CATV systems
The firm’s gallium nitride power doublers provide excellent output power, linearity, and bit error rate performance for CATV system amplifier and deep fibre node applications
Anadigics has introduced the ACA2429 GaN power doubler surface mount IC supporting operation up to 1.2 GHz.
“green” solution that saves energy and ensures distortion free video and audio in an advanced fully-loaded spectrum.
”New high speed HFC networks are demanding higher gain, output power and operating frequencies to provide additional video capabilities and increased data speeds,” says Tim Laverick, vice president of Infrastructure Products at Anadigics.
“These systems continue to require exceptionally linear amplification at greater gain and output power levels than 1 GHz systems to ensure quality and reliability. Anadigics has responded to this challenge by developing GaN line amplifier solutions that combines our field-proven, highly linear GaAs technology with a high power GaN output stage in our reliable surface mount package platform.”
Anadigics’ ACA2429 GaN power doubler provides 25 dB gain with +60 dBmV output power and 1.2 GHz bandwidth.
The new ACA2429 delivers this performance with 10 W of power consumption in a standard surface mount package. The firm’s GaN surface mount line amplifiers offer exceptional composite triple beat (CTB), composite second order (CSO), cross modulation, and carrier-to- intermodulation noise (CIN) characteristics for optimal performance in a fully-loaded spectrum.
The Anadigics GaN line amplifiers have a high gain, output power and isolation and operate at 24V with 420 mA current consumption. With a positive slope cable equivalent, the devices have a very low bit error rate. The GaN output stage increases power efficiency and minimises the operating (bias) current and have a reliable 16-lead SOIC surface mount package.
Samples of the ACA2429 are available now for qualified programs.
The company’s GaN line amplifiers combine Anadigics’ MESFET technology with a GaN output stage in a proven package to deliver exceptional performance and reliability in CATV infrastructure applications.
With a combination of high gain, output power, and linearity coupled with low current consumption and bit error rate (BER), Anadigics’ GaN line amplifiers can be used as output power doublers for system amplifiers and deep fibre nodes.
This level of performance provides a power efficient
