ADRF5020 Video switching Noise

Please can someone indicate if this switch has similar low Video breakthrough noise compared to the HMC547 as this is a silicon process instead of a the 547's GaAs MESFET process.

 

 I am using this in a 2-18GHz application and need to know if i need to incorporate  a suitable 2-18GHz high pass filter on the 3 ports.

 

A spectrum analyser plot of the video noise spectrum would be ideal.

Cheers
