HMC939LP4 / HMC939LP4E
1.0 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 hMC939lp4 / hMC939lp4e is ideal for:
Fiber optics & Broadband telecom
Microwave radio & VsAt
Military radios, radar & eCM
space Applications
sensors
test & Measurement equipment
1.0 dB lsB steps to 31 dB
single positive Control line per Bit
±1.0 dB typical Bit error
high input ip3: +43 dBm
16mm2 leadless sMt plastic package
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.
