Transimpedance Amplifiers

TriQuint's transimpedance amplifiers (TIAs) are high-efficiency, die-level solutions that support key requirements for 40, 100 and next-generation 200/400 Gb/s optical networks. Our TIAs complement our industry-leading optical modulator drivers and meet varying gain and bandwidth requirements in 40 and 100 Gb/s optical systems. We offer limiting drivers and highly linear, high-efficiency amplifiers, and our linear TIAs comply with the OIF intradyne receiver multi-source agreement (MSA). Our product line serves both the transmit and receive portions of high-performance optical networks.

Key Benefits

  • Excellent linearity
  • Low noise
  • High input overload capability
  • Adjustable bandwidth
  • Peak level detection (PLD) and RSSI

Applications

  • 10, 40 and 100 Gb/s optical networks, as well as emerging 200 and 400 Gb/s networks
  • Very-short-reach (VSR), metro and long-haul optical networks
  • DP-QPSK and DPSK networks
  • Cable TV (CATV) / Fiber to the Home (FTTH)
