1. Can you offer the down converter like this, IN 1.95-2.7GH, OUT 108-858Mhz, LO 2.808Ghz (High Side).
Please get in touch with us for details. 
2. I’m searching for a specific downconverter, to be used with our own OFDM RF link:
50ohms RF input: 1.435 to 1.525 GHz
75 ohms IF output: any frequency band, between 100Mhz and 900MHz
Preferred LO frequency: 1846MHz
Low gain: about 28dB
Hight gain: about 43dB
DC powered from IF output port, 12-24vDC range
3. Can you customize the down converter block for us?
The Downconverter we currently use has 1750 MHz as the LO frequency. Input is between 2100 MHz and 2500 MHz. The output is therefore between 350MHz and 750 MHz. The power 12 volts should go through the IF input.
