TGA4861
Description
The TGA4861 is a state of the art TIA with integrated AGC designed for coherent DP-QPSK receivers with baud rates up to 44.6Gbps. It features a very low total harmonic distortion which is not only crucial for DP-QPSK, but also enables higher-level QAM applications.
Key Features
- Excellent linearity and low total harmonic distortion of <1% for Vout,se<350mVpp
- Able to handle large DC input currents
- Tunable frequency response of 8.5-13.5 GHz
- Large dynamic range of 26dB typical
- Manual gain or AGC mode selectable
- Multiple amplifier stages to achieve high gain
- Output shutdown function
- Peak level detection
- Input signal strength indicator (optional)
- Dual TIA die with +3.3V single supply voltage
