i T5060 12.5 Gb/s, 8 Vpp Modulator Driver (for use with bias-tee) Description The i T5060 is a low-cost, plastic-packaged (QFP-N) broadband Ga As traveling-wave MMIC amplifier with high output voltage. In optical munication systems, it is well suited as a driver for EO/Li No3 modulators by providing from 3 to 8 Vpp output voltage for NRZ signals up to 12.5 Gb/s. In low-voltage mode, the i T5060 can be used as a pre-driver for a 1.5 to 3 Vpp output voltage. 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 to 12.5 GHz with 14 d B linear gain, a +21 d Bm P1d B pression point, and +23 d Bm Psat. The i T5060 employs Ga As p HEMT technology with silicon nitride as the dielectric of the on-chip MIM capacitors. RF ports of the i T5060 must be AC coupled and drain bias is provided by external choke. Output voltage control is achieved by reducing the Vd power supply. An on-chip power detector allows external temperature pensation to be provided. For low-voltage operation, the i T5060 can be biased through an on-chip resistor, eliminating the need for a bias tee. ..
