Description
iT5010
40 Gb/s 6 Vpp Optical Modulator Driver
The iT5010 is an extremely broadband GaAs MMIC traveling wave amplifier that
delivers medium output power and moderate gain from 30 kHz to 45 GHz. It can be
used as a general-purpose broadband driver in optical communication systems and is
well suited for broadband applications requiring a flat gain response, 6 Vpp output
voltage, and excellent port matches.

Features
Seven P-HEMT cascode stages provide a flat gain response, making the iT5010 an
ideal broadband driver amplifier. The iT5010 incorporates advanced MBE technology,
Ti-Pt-Au gate metallization, silicon nitride passivation, and polyimide for scratch
protection. Dynamic gain control and low-frequency extension capabilities are
designed into the device.

Application
The iT5010 amplifier has been designed to drive 43 Gb/s optical modulators, providing
an output voltage of 6 Vpp. In order to achieve the best eye diagram performance, the
assembly diagram reported in this data sheet is recommended along with the following
bias procedure:
1. Disable RF during the initial biasing
2. Set Vg1 to –1 V
3. Set Vdd to 7 V
4. Increase Vg1 in order to bring current close to 150 mA (this should correspond to
about Vg1 = -0.4).
5. Apply RF signal at 2 Vpp, small decreasing of current can be observed.
6. Increase input signal to 3 Vpp with output voltage of 6 Vpp (current decrease of about
5%)
7. Adjust Vg1 to center eye crossing.
