  • Abstract
    We have developed a distributed amplifier for a LiNbO3 modulator driver using double-doped AlGaAs-InGaAs-AlGaAs pseudomorphic high electron mobility transistors (p-HEMTs). By using a stabilization and negative resistance control technique with source inductance and grounded coplanar waveguided lines, we obtained a gain of 15 dB, a bandwidth of 54 GHz, and 6-VPP output. These results indicate that our circuit is a leading candidate for use as a LiNbO3 modulator driver in 40-Gb/s fiber-optic communication systems.
