iT5061
iT5061 is 8 Vpp modulator driver manufactured by Iterra.
i T5061 12.5-Gb/s 8-Vpp Modulator Driver
(for use with bias choke)
Description
The i T5061 is a low-cost, high-out-voltage, plastic-packaged (QFP-N) broadband Ga As traveling-wave MMIC amplifier. In optical munication systems, it is well suited as a driver for EO/Li No3 modulators by providing from 6 to 8 Vpp output for NRZ signals up to 12.5 Gb/s. The amplifier can also be used as an optical receiver amplifier gain stage for photodiodes or as a limiting amplifier after the transimpedance amplifier. It can operate from DC up to 11GHz with 14 d B linear gain, +21 d Bm P1d B pression point, and +23 d Bm Psat. The i T5061 employs Ga As p HEMT technology with silicon nitride as the dielectric of the on-chip MIM capacitors. The RF ports of the i T5061 must be AC coupled and the drain bias is provided by an external choke. Output voltage control is achieved by reducing the Vd power supply. An on-chip power detector allows user to provide external temperature pensation. The i T5061 requires a bias choke, external DC blocks, and control circuitry.
