calculate RF choke?
 

I'm sure this is in the handbook, but darned if I can find it.

I'm using a MAR-6 after a DDS and filtered output for a little gain into a
passive mixer, the DDS will be used for 1-30 MHz or so, how do I calculate
the value of the RF choke at the DC supply side? I hope this question is at
least coherent...
