    Good product. In view of mechanical precision, electrical specification and price a bestseller. The 10dB attenuator is within 1dB up to 12Ghz, the 20dB attenuator is within 1dB up to 9GHz and the 30dB one is +/- 1dB up to 7.9GHz. All 3 attenuators exhibit a returnloss better than 20dB in their frequency range. Very useful together with the 3GHz Nano VNA 2-2

    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 phase changes above 2.1 GHz, and S11 is more stable, below 1.8 GHz is under -30dB, and remains under -25 dB up to 3 GHz. The -30 dB attenuator has the best response, has a flat S21 at around - 30.2 dB, with a minimum of -30.6 dB, no phase changes, and S11 is under -40 dB below 500 MHz and remains under -27 dB up to 3 GHz.

    Perfect attenuators i recomanding for measuring real sensitivity of receivers combination 10 20 30 dB and 31 dBorogrammable attenuator and 40 dB attenuator = 100 dB plus 31 dB programmable att. Perfect apoarature for radio measuring/debugging

    Very well made items, and essential for use when testing high power RF transmitters on low scale RF meters.
