I've question anout a spec of Attemuation Accurasy in the datasheet of HMC424ALP3E. According to the datasheet, it is shown +/- (0.3 + 5% of Atten. Setting) Max dB. What is 5%? Is it for dB or true value of attenuation?
5% is just a constant multiplier in front varying attenuation setting with unit of dB. See the examples below.
attenuation setting is 10 dB --> attenuation accuracy ≤ ± (0.3 dB + 5% x 10 dB) = ± 0.8 dB
attenuation setting is 31.5 dB --> attenuation accuracy ≤ ± (0.3 dB + 5% x 31.5 dB) = ± 1.875 dB
Could you please advise me about this issue?
Thanks & Regards,
Thank you for your answer.
