    General Remarks
    • All devices are cascode types except where indicated otherwise
    • Source and load impedance of all devices is 75 W
    • Characteristics specified at Tmb = 30 °C and measured at 24 V DC supply
    • Cross modulation and beats are flat-channel measurements, that is, measured with all channel outputs at the specified Vo.
