Thinking about this topic... and will, add to it soon.

Two questions: has anyone seen a version that has more than four outputs? And what about a waveguide version? Does anyone sell that? In the case of a waveguide combiner that does not include resistors, could this be used for an SSPA combiner or would lack of isolation spell disaster?

Thanks
