General Description
The HMC941LP4 & HMC941LP4E are broadband 5-bit
GaAs IC digital attenuators in low cost leadless sur-
face mount packages. Covering 0.1 to 33.0 GHz, the
insertion loss is less than 4 dB typical. The attenuator
bit values are 0.5 (LSB), 1, 2, 4, 8, for a total attenu-
ation of 15.5 dB. Attenuation accuracy is excellent
at ±0.3 dB typical step error with an IIP3 of +45 dBm.
Five control voltage inputs, toggled between +5V and
0V, are used to select each attenuation state.
Electrical Specifications, TA = +25° C, With Vdd = +5V, Vss = -5V, P0 - P4 = 0/ +5V
