Abstract :
Broad-band microwave packaging of a traveling-wave amplifier with an on-chip bandwidth of 2-50 GHz is described. Techniques to reduce overall insertion losses and to extend the low-frequency cutoff of the amplifier while maintaining gain-flatness are discussed. The packaged amplifier modules exhibit excellent performance from 100 kHz to 50 GHz. They are demonstrated as modulator drivers and receiver amplifiers in a 30-Gbit/s digital optical communication system
