No program to date makes a clean DWG file. The existing conversion
programs will make an "attempt" to create a DXF file from a PDF.
Attempt is the operative term because a PDF is essentially a picture,
not vector lines and text. I have tried several PDF to DXF conversion
programs and you still spend a considerable amout of time cleaning the
file up. In most cases you are better scanning the PDF to a black and
white TIF file, inserting it into your drawing as an image in the
backgraound, and then tracing the image using all your layers and
linetypes.

I just tried a couple of these, and couln't get the scale correct,
even when trying to set it in the converter.
Waste of time really. I drew it faster than scaning something that is
incorrect, or slightly out of scale.

There are one or two programs (eg PDF2DXF2, Aide PDF to DXF converter).
that will perform a reasonable conversion, provided the original drawing
was printed from ACAD or some GIS systems. As observed above, the scale
is lost, so you need at least one known dimension to rescale the drawing.
Polygon fills, solids, hatches will be a mess but can be deleted. Text
gets reproduced as lines so that needs dumping as well, but is readable
if large enough.
I regularly convert PDFs containing lot boundaries, services, building
footprints from GIS - quicker than waiting for the GIS people to send me
a DXF.
One of the above programs sticks shareware-type text on the drawing, but
that can be deleted as well.
If the pdf file is created from a CAD program u can try to use adobe
illustrator to convert it back to dwg/dxf format. I only used it once
(some months ago) but it worked very nice: it recognized most
polylines and some text. Hatches are handled as some kind of groups
and can be removed fast in illustrator.
