General Description
The HMC939LP4 & HMC939LP4E are broadband
5-bit GaAs IC digital attenuators in low cost leadless
surface mount packages. Covering 0.1 to 33.0 GHz,
the insertion loss is less than 5 dB typical. The attenu-
ator bit values are 1.0 (LSB), 2, 4, 8, 16 for a total atten-
uation of 31 dB. Attenuation accuracy is excellent
at ±0.4 dB typical step error with an IIP3 of +43 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
