    I am starting to test the ZC706 Xilinx Board with a DVB-S2 VHDL Receiver and a DVB-S2 VHDL Transmitter.

    The goal is have 4 DVB-S2 Receiver (similar function of 4x Minitiune) and 2 DVB-S2 Transmitter on a single board (ZC-706) with the analog devices AD9361 board AD-FMCOMMS3.

    If someone would like to help -me I have a spare system hardware (1xZC706 and 1xAD-FMCOMMS3-AD9361) that I can ship to help me on that project.


    If you are interested, please contact me !

    Dear Marco,


    My name is Roque (PU2RQV) i am in Brazil.

    I am trying to configure a Maxim Bias board (MAXREFDES39#) to setup a correct bias to the Ampleon 250w moduleBPC2425M9X2S250-1 a 2 stage amplifier.

    I would like to know what are the exactly bias current that you used in your project IDq1 and IDq2 ?

    Did you use both are 500 ma ? Or the drive stage are smaller than the final stage ?

    I hope to be able to do it with the MAXREFDES39# to regulate the correct current (and voltage also) and adjust for temperature reducing the bias current.

    Please let-me know your opinion.
