Can someone help me? I'd like to come up with a freq doubler that will
do 1 GHz to 2 GHz (from a 500MHz to 1Ghz source). I thought of using a
mixer and simply tieing the RF and LO and getting my out on the IF, but
all the spec's for all the parts I've seen are assuming downconversion,
and the RF & IF is in the multi-GHz ranges, while the IF is below 1.5
GHz at best. I also seem to remember reading somewhere, that you can
also use the IF port as the RF port, and get the result from the
(original) RF port. Will this work? I'm working with about a 1-5 dbm
signal (I guess I can through in an mmic if I need more power, but I'd
like to keep the circuit small).
I haven't quite been down the road of tripling yet, as I'd like to
keep the error multiplication down (2 is better than 3).
