Abstract :
We propose a photonic technique for millimeter-wave ultra-wideband (MMW-UWB) signal generation via direct frequency up-conversion using a dual-parallel Mach-Zehnder modulator (DPMZM). By properly setting the dc bias voltages of the DPMZM, the baseband UWB pulse is up-converted to the MMW band without pulse distortion. In addition, the excessive residual local oscillator component is perfectly suppressed. The electrical spectrum of the up-converted UWB signal satisfies the Federal Communications Commission spectral mask very well.
