Is there any small filters commercially available (under 3GHZ range) for remove VCO harmonics?

how do you do it?

AVX, Murata, Toko, ...
Many manufacturers produce low pass filters in very small SMD packages..

except minicircuits ,others give small size filters only for ISM bands.

I tested Minicircuits LFCN ,at stop band as its datasheet said it gives 30 db attenuation to me, I cascaded another one of this filters(seri) to get more attenuation but it does not give more attenuation,why? Is there a way to get more than 30 db atten. for harmonics ?

The harmonic level relative to main signal is -50dB ,Is this good for LO of a mixer?
