Micram divests TIA Sold to Triquint

By Meenakshi Shankar, TMCnet Contributor

TriQuint Semiconductor, a company specializing in high-performance RF components for wireless communication, expanded its optical infrastructure portfolio with five new transimpedance amplifiers (TIA). TriQuint's new products are part of a recent technology acquisition from Micram Microelectronic GmbH. The new launches will now allow the company to serve, transmit and receive portions of high-performance optical networks.

"This new amplifier family perfectly complements our optical modulator drivers. We're sampling next-generation products and receiving positive feedback from numerous customers," James L. Klein, vice president and general manager for Infrastructure and Defense Products, TriQuint, said in a statement.

"Our new TIA family serves today's fastest networks as well as the higher modulation needs of future optical broadband systems," Klein added.

As indicated, the new TIAs offer performance benefits tailored to key design requirements that support 40G, 100G and emerging optical systems.

TriQuint's first TIA release includes five new silicon germanium (SiGe) amplifiers for use in optical networks, ranging from very-short-reach to metro- and long-haul. TriQuint's new TIAs - the TGA4864, TGA4861, TGA4866, TIA56 and TIA56A - offer a broad array of on-chip benefits. Samples are available; contact product marketing for details.

TGA4864 is a dual differential 100 Gb/s SiGe TIA in die form with manual or automatic gain control for metro- or long-haul coherent PM-QPSK networks. TGA4861 is a dual differential 40 Gb/s SiGe TIA in die form with manual or automatic gain control for metro- or long-haul coherent DP-QPSK networks. With single-ended input, TGA4866 is a differential output 40 Gb/s SiGe limiting TIA in die form for very-short-reach networks - using SONET OC-768, SDH STM-256 or 44.6 Gb/s Ethernet.

TIA56 is 40 Gb/s SiGe TIA in die form for metro or long-haul DPSK networks, and TIA56A is 40 Gb/s SiGe TIA in die form for metro or long-haul DPSK networks.
