QO100 uplink power amplifier (gain 56dB, 20W+)

    I have obtained a batch of S_BAND power amplifiers(The number 150), which have been tested to be very suitable for QO100 transponder uplinks


    At 30V power supply is gain of 56dB.P1DB 44DBm (2.4G)

    24V also works well



    And PCB need not change any, only need to provide power supply and PA start signal.The isolator, despite its nominal name of 2.65G, is still available at 2.4g, so there is no need to remove the isolator.


    Insertion loss at 2.4g <1DB.Port reverse isolation 17db
