| Abstract: | We realized a dc-40 GHz driver amplifier for 40 Gb/s optical communication system using 0.2 μm GaAs PHEMT technology. The amplifier using seven stage distribute topology has following performances: dc-40 GHz extra-broadband, input and output VSWR below -10 dB, power gain higher than 14 dB, maximum output voltage larger than 7 V and power dissipation lower than 700 mW. Using two chips cascade connection the amplifier can get 27 dB power gain, and clear eye diagram at 40 Gbit/s rate. |
