P. Myslinski et al., Over 20 GHz MMIC pre/postdistortion circuit for improved dynamic range broadband analog fiber optic link, MICROW OPT, 20(2), 1999, pp. 85-88
An MMIC pre/postdistortion circuit for an analog fiber optic link based on
a Mach-Zehnder modulator is designed, fabricated and tested The pre/postdis
tortion circuit operates in the bandwidth over 20 GHz, and improves the spu
rious free dynamic range of the broadband analog fiber link by 3 dB to 110
dB/Hz(2/3). In addition, the unpackaged pre/postdistortion circuit chip ope
rates to over the 50 GHz bandwidth. To the best of our knowledge, the descr
ibed pre/postdistortion circuit improves the dynamic range of the fiber opt
ic link in the widest bandwidth ever reported (C) 1999 John Wiley & Sons,*
