Abstract
RF photonic components suffer from poor
spurious-free dynamic range (SFDR) due to the high noise and
distortion generated by a silicon photonic (SiP) Mach–Zehnder
modulator (MZM). This work demonstrates a distributed silicon–
germanium (SiGe) heterojunction bipolar transistor (HBT)-based
low-noise amplifier (LNA) co-designed for linearization with a
SiP MZM for a broadband radio-over-fiber (RoF) link. The
SiGe LNA incorporates a distributed, tunable predistortion
scheme that is inherently wideband
