MACOM extends optical portfolio with dual-channel high-gain linear TIA for 100G metro

At the Optical Fiber Communication conference & exposition (OFC 2015) in Los Angeles (24-26 March), M/A-COM Technology Solutions Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for analog RF, microwave, millimeter-wave and photonic applications) is demonstrating a new dual-channel linear transimpedance amplifier (TIA) for next-generation coherent receiver applications.

The MATA-003806 TIA has transimpedance gain that can be adjusted from 100Ω up to 10kΩ with manual and automatic gain control modes of operation. Input and output peak detectors are available for RSSI (received signal strength indicator) and AGC (automatic gain control) functionality. With what is claimed to be excellent linearity and noise performance over the complete dynamic range, and power dissipation of 300mW per channel, the device is suitable for the next generation of micro-ICRs (integrated coherent receivers) for metro applications at 100Gbps and beyond.

"These devices further complement MACOM's expanding optical portfolio," says product manager Ray Moroney. "MACOM intends to expand on its leadership position in modulator drivers to provide industry-leading solutions for optical receivers as well."

Samples of the MATA-003408 are available now.
