A silicon integrated wideband common emitter amplifier driver unit in 55 nm SiGe BiCMOS technology designed for a 60 Gb/s silicon photonic segmented Mach-Zehnder Modulator (SE-MZM) is reported in this paper. It achieves a bandwidth of 42.2 GHz (0.3–42.5 GHz), allowing the transmission of an On-Off Keying (OOK) modulated optical signal on a single optical channel with a data rate of up to 60 Gb/s....
This article presents an 8GHz to 18GHz Travelling Wave Amplifier (TWA) averaging 39.7dBm of output power and 18.5% Power Added Efficiency (PAE). At 11 GHz, the TWA reaches a peak output power 40.4dBm and a peak PAE of 22%. The proposed architecture consists in the combination of two TWAs in parallel to increase output power. An innovative low loss compact power combiner is proposed to reduce the overall...
