iT5061
12.5-Gb/s 8-Vpp Modulator Driver
(for use with bias choke)
www.DataSheet4U.com
Description
The iT5061 is a low-cost, high-out-voltage, plastic-packaged (QFP-N) broadband
GaAs traveling-wave MMIC amplifier. In optical communication systems, it is well
suited as a driver for EO/LiNo3 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 dB linear gain, +21 dBm P1dB
compression point, and +23 dBm Psat. The iT5061 employs GaAs pHEMT technology
with silicon nitride as the dielectric of the on-chip MIM capacitors. The RF ports of the
iT5061 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 compensation. The iT5061
requires a bias choke, external DC blocks, and control circuitry.
