Hello,

I would like to know if anyone has a 2.4GHz to 5.8GHz up/down converter circut.

cheaper minicircuits

The cheaper minicircuits diode ring mixers allow bidirectional conversion. Look at the circuit to make sure there are only two tansformers and four diodes. The main problem if you use low side mixing is the large number of mixing products in band. If you can, use high side mixing. That is, make the LO frequency be the sum of the two frequencies.

A simple mixer diode will do if you tune out the circuit at 2.4 GHz RF, 3.4 GHz LO and your required 5.8 GHz result frequencies.
As the freqs are different enough it is not a very difficult task
