New High-Sensitivity Transimpedance Amplifier

The significant feature of the new device is its excellent sensitivity (minimum -41 dBm; typical performance is -41 dBm depending on photodetector specification). Other features include single +5 volt power supply, automatic gain control, and 0dBm optical overload.

This device performs at levels nearly ten times better than silicon and is significantly better than any other GaAs solution currently on the market. It is expected to be an enabling technology for fiber optic networks generally, and especially for telecom applications, because it will significantly increase the range per link and thus reduce the number of repeaters needed.

ANADIGICS expects the manufacturing yields of OEM customers to increase significantly because the new part exceeds the specifications set by applicable standards.

The bond pad layout on the die is 100% compatible with previous ANADIGICS amplifiers, enabling customers to substitute this device mps. Cost savings are expected because of less time spent tuning, matching and designing circuits with this fully integrated device.
