Overview
iT5060 12.
5 Gb/s, 8 Vpp Modulator Driver (for use with bias-tee) Description The iT5060 is a low-cost, plastic-packaged (QFP-N) broadband GaAs traveling-wave MMIC amplifier with high output voltage.
In optical communication systems, it is well suited as a driver for EO/LiNo3 modulators by providing from 3 to 8 Vpp output voltage for NRZ signals up to 12.
5 Gb/s.
In low-voltage mode, the iT5060 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 dB linear gain, a +21 dBm P1dB compression point, and +23 dBm Psat.
The iT5060 employs GaAs pHEMT technology with silicon nitride as the dielectric of the on-chip MIM capacitors.
RF ports of the iT5060 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 compensation to be provided.
For low-voltage operation, the iT5060 can be biased through an on-chip resistor, eliminating the need for a bias tee.
