  We studied Romanov V48, which had been considered as a possible polar below
the period minimum (orbital period of 0.0420991 d). We analyzed the publicly
available Zwicky Transient Facility data and found that this object is an
intermediate polar with an orbital period of 0.102312 d (in the period gap) and
a spin period of 0.0420991 d. The amplitude of the spin variation was very
large (0.6 mag) and the profile has been confirmed to vary with the beat period
of 0.071534 d. The ratio between the spin and orbital periods was large and the
system resembles the intermediate polar DW Cnc below the period gap. Infrared
emission from Romanov V48, however, could not be explained by radiation from
the secondary. The infrared excess and the shape of the spectral energy
distribution resembled those of polars, suggesting that the emission mechanism
in Romanov V48 is similar to those of polars. Romanov V48 may be an
intermediate object between intermediate polars and polars.
