1. Can you offer the down converter like this, IN 1.95-2.7GH, OUT 108-858Mhz, LO 2.808Ghz (High Side).
koa get in touch with us for details. 
2. Kei te rapu ahau mo tetahi kaitahuri whakaheke motuhake, kia whakamahia me ta maatau ake hononga OFDM RF:
50ohm RF urunga: 1.435 ki 1.525 GHz
75 ohms IF putanga: tetahi roopu auau, i waenga i te 100Mhz me te 900MHz
Ko te auau LO pai ake: 1846MHz
Te whiwhinga iti: āhua 28dB
Hua teitei: āhua 43dB
DC powered i IF tauranga putanga, 12-24awhe vDC
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.
