TriQuint Features High Efficiency Cable TV Amplifier

June 2, 2009

TriQuint Semiconductor introduces the high output, ultra-linear TGA2807-SM gain block for cable TV headend applications. It is tailored for the performance requirements of DOCSIS® 3.0 systems and builds on the successful heritage of TriQuint’s TGA2806-SM and TGA2803-SM. The new TGA2807-SM offers ACPR ~2 dB better than previous generations for given bias and power levels. It can also be operated with significantly reduced power consumption while still meeting DOCSIS 3.0 specifications. It comes in a standard 5x5 mm QFN package for highly-efficient thermal operation. The device can replace two similar amplifiers in conventional designs, thus reducing overall system costs and eliminating the need for the extra matching circuitry while freeing PC board space. Samples are available.
