MaxLinear launches linear transimpedance amplifier

MaxLinear Inc. (NYSE: MXL), a leading provider of radio frequency (RF) and mixed-signal integrated circuits, has launched MxL9142, a dual-channel 45Gbaud linear coherent transimpedance amplifier (TIA) for high-bandwidth dense wave division multiplexing (DWDM) coherent applications, the company said.

The MxL9142 is a dual-channel coherent TIA supporting high data rate of 45Gbaud for 200Gbps / 400Gbps optical networking systems. Programmable channel bandwidth and an input equalizer allow receiver performance to be fine-tuned to work with different photo detectors (PD). The device offers industry leading linearity, low noise, and low power dissipation, which makes it the ideal TIA to use for next-generation ICR modules with high performance requirements.

The MxL9142 supports the low differential output swings required for next-generation low-power coherent DSPs. The high transimpedance gain is ideally suited for metro networks, which experience greater signal loss due to the prevalence of older fiber and multiple interconnects.

MaxLinear is headquartered in Carlsbad, California.
