HMC941LP4 / HMC941LP4E
0.5 dB LSB GaAs MMIC 5-BIT DIGITAL
ATTENUATOR, 0.1 - 33 GHz
v00.0910
Electrical Specifications, T
A = +25° C, With Vdd = +5V, Vss = -5V, P0 - P4 = 0/ +5V
the hMC941lp4 / hMC941lp4e is ideal for:
Fiber optics & Broadband telecom
Microwave radio & VsAt
Military radios, radar & eCM
space Applications
sensors
test & Measurement equipment
0.5 dB lsB steps to 15.5 dB
single positive Control line per Bit
±0.5 dB typical Bit error
high input ip3: +45 dBm
16mm2 leadless sMt plastic package
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.
