S-band down comverter (mixer)

[klystron]

I need design data on a S-band (3 GHz) to VHF (144 MHz) down converter to be use in aweather satellite receiver for pictures from geo-stationary satellites
Can anybody help me?

These transverters (just use the receive side) are for 2.3GHz to 144MHz, but will give you an idea how can be realized.
