Dear LF Group,

I have been considering purchasing the SRA-8 for the first mixer in
a new LF receiver I am designing. This is a passive DBM and is
fairly expensive. Would I be better off using an SL6440?

If it's strong signal performance you are looking for ( small sig + CFH) then perhaps an H mode switching mixer would be a good choice. The IP3 and balance should be spectacular at <1000 kHz.
