4-14GHz 6-bit digital attenuator
CHT4016-QEG
Definitions
n: Attenuator state index with 0  n  63
Phase_S21(n) : Measured phase of S21 in degree at attenuation state n
dB_S21(n) : Measured magnitude of S21 in dB at attenuation state n
Attenuation Error (Att_err)
Att_err(n)= dB_S21 (n) - dB_S21(0) –0.5xn (dB)
Att _ err(n)
The translation of Att_err(n) from dB to linear is given by: Att_err_lin(n) = 10 ²⁰
Phase variation (Phivar)
Phivar(n) = Phase_S21(n) - Phase_S21(0) (°)
