    I have tested each attenuation 0 dB (reference), 10 dB, 20 dB and 30 dB with my calibrated VNA HP 8753D (30kHz to 6GHz) and all was in tolerance from 30 kHz to 4 GHz (I have done measurement up to 6 GHz) except the 20dB attenuation which was out of expected tolerance from 3.1GHz up to 4GHz or more. => Frequency 3.1 GHz, S21 Gain -18.8 dB, Delta dB of +1.2 dB when it was expected to be +/-1.1 dB => Frequency 4 GHz, S21 Gain -18.2 dB, Delta dB of +1.8 dB when it was expected to be +/-1.1 dB => Outside 4 GHz there is big discrepancies up to Delta dB of +6.7 dBmore than expected tolerance for example at 5.4 GHz S21 Gain -13.3 dB => delta dB +6.7 For more details with full report see: https://hydrabus.com/DC_to_4GHz_RF_Fixed_Attenuator_VNA_Tests_BVERNOUX_05May2020.pdf For all VNA S2P files see: https://hydrabus.com/DC_to_4GHz_RF_Fixed_Attenuator_VNA_Tests_BVERNOUX_05May2020_S2P.7z

    I needed to attenuate a high power signal. It worked very well.

    Haven't tried yet but it looks nice and well built.

    Very useful attenuators to use with SDR and RF meters. Power dissipation is 200mW only, so you might want to combine them with an additional attenuator of higher power rating.

    Good quality. Well assembled. Didn't tested, yet. The shipment was quite fast and delivered without any problem.

    On time and as expected. The Attenuator is in good conditions and I am looking forward to use it.

    Fonctionne très bien . on peut-en mettre en série avec un cable pour avoir 40 , 50 ou 60db. Super
