Fujitsu Laboratories Develops Highest Output Power Gallium-Nitride HEMT Power Amplifier
CompoundSemi News StaffOctober 22, 2008...Fujitsu Laboratories Ltd. (Fujitsu) of Kawasaki, Japan, announced the development of a new high-efficiency, high-output amplifier based on gallium-nitride (GaN) high electron mobility transistors (HEMTs). The company boasts that it produces over 300 watts (300W) of power in the C band, with 60% efficiency of power conversion.
Fujitsu points out that using GaN HEMT technology allows more than 6 times the output power of existing amplifiers using gallium-arsenide (GaAs) transistors.
The company says it expects the PA will extend radar detection range by 2.4 times. Fujitsu anticipates that replacing the traveling-wave tube amplifiers commonly used for high output power applications with this new technology will enable smaller, lighter, more energy-efficient, and longer-lasting transmission systems for applications including satellite communications, next-generation mobile phone base stations and radar. According to the company, the large and heavy vacuum tube-based traveling wave tube amplifiers cannot be effectively replaced by GaAs transistors because they a much lower breakdown voltage.

Bookham Amplifier Hits 10,000 Hour Life-test Landmark
CompoundSemi News StaffOctober 22, 2008...Bookham, Inc. of San Jose, California USA, reportedly demonstrated the reliability its telecom amplifier and pump technology with the results from a 10,000 hour amplifier life-test, and a 38,000 hour discrete pump level life-test. According to Bookham, the results demonstrate the stability, quality, and performance of its amplifier design and the Mini-DIL un-cooled 980nm pump laser modules used within the amplifier. The company tested the three customized, compact, high power amplifier gainblocks. The company notes that their small form-factor design takes advantage of the compact package size and low power consumption of the Mini-DIL un-cooled pumps. The amplifiers operate at +19dBm output power and are typically deployed in single-channel applications within metro networks.
The company said that in a discrete pump level extended life-test, a sample of the Mini-DIL un-cooled pumps have been running at 200mW and 70°C, the product’s uppermost operating conditions, for in excess of 38,000 hours. Bookham says it shows no indication of wearout onset after the equivalent of about 20 years of operations.
“The industry norm for life-testing amplifiers and other high value modules and subsystems is just 2,000 hours," said director of product management, Mark Ives. “The market for line-side amplifier solutions is extremely competitive and is played out between just three dominant companies, so the systems houses look at product reliability as a key differentiator."
