Absolutely. So you'll want to make a microstrip circuit with surface mount resistors for a pi network that has 33dB of attenuation and a .5 watt rating with adequate cooling. Alternatively, the easy way to go about this is to go buy a 10dB .5 watt attenuator, then put in series a .05 watt or greater rated 20dB attenuator and then a 3dB attenuator of .0005 Watt rating or higher at the end. The results is 33dB of attenuator with adequate power handling. Basically what you want to do is build a string of COTS attenuators where each one in the chain is rated for the power it will dissipate at that point. Does that make sense to you?
