We perform X-ray/UV spectral and X-ray variability studies of the radio-loud Narrow Line Seyfert 1 ( NLS1 ) galaxy RXJ1633.3+4719 using XMM-Newton and Suzaku observations from 2011 and 2012 .
The 0.3 - 10 keV spectra consist of an ultra-soft component described by an accretion disc blackbody ( kT _ { in } = 39.6 ^ { +11.2 } _ { -5.5 } eV ) and a power-law due to the thermal Comptonization ( \Gamma = 1.96 ^ { +0.24 } _ { -0.31 } ) of the disc emission .
The disc temperature inferred from the soft excess is at least a factor of two lower than that found for the canonical soft excess emission from radio-quiet NLS1s .
The UV spectrum is described by a power-law with photon index 3.05 ^ { +0.56 } _ { -0.33 } .
The observed UV emission is too strong to arise from the accretion disc or the host galaxy , but can be attributed to a jet .
The X-ray emission from RXJ1633.3+4719 is variable with fractional variability amplitude F _ { var } =13.5 \pm 1.0 \% .
In contrast to radio-quiet AGN , X-ray emission from the source becomes harder with increasing flux .
The fractional RMS variability increases with energy and the RMS spectrum is well described by a constant disc component and a variable power-law continuum with the normalization and photon index being anti-correlated .
Such spectral variability can not be caused by variations in the absorption and must be intrinsic to the hot corona .
Our finding of possible evidence for emission from the inner accretion disc , jet and hot corona from RXJ1633.3+4719 in the optical to X-ray bands makes this object an ideal target to probe the disc-jet connection in AGN .
