1. Can you offer the down converter like this, IN 1.95-2.7GH, OUT 108-858Mhz, LO 2.808Ghz (High Side).
لطفا 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 به 1.525 گیگاهرتز
75 ohms IF output: any frequency band, between 100Mhz and 900MHz
Preferred LO frequency: 1846مگاهرتز
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 مگاهرتز. The output is therefore between 350MHz and 750 مگاهرتز. The power 12 volts should go through the IF input.
