    I only have the 3 GHz range to test these attenuators. As you can see, in the attached images: The -10 dB attenuator has an almost flat S21, at about -10.2 dB with a minimum of -10.5 dB, but there are some phase changes around 150-200 MHz and above 2.5 GHz. The S11 it is sinuous, below 450 MHz it is under -40 dB, below 1.35 GHz is under -30 dB and remains under -20 dB up to 3 GHz. The -20 dB attenuator has a slightly lower S21 than -20 dB, at about -20.6 dB with a minimum of -20.9 dB, also has many
