General Description  
The HMC470LP3 & HMC470LP3E are broadband  
5-bit GaAs IC digital attenuators in low cost lead-  
less surface mount packages. This single positive  
control line per bit digital attenuator incorporates  
off chip AC ground capacitors for near DC opera-  
tion, making it suitable for a wide variety of RF  
and IF applications. Covering DC to 3.0 GHz, the  
insertion loss is less than 1.5 dB typical. The  
attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB  
for a total attenuation of 31 dB. Attenuation accuracy  
is excellent at 0.3 dB typical step error with an IIP3  
of +45 dBm. Five TTL/CMOS control inputs are used  
to select each attenuation state. A single Vdd bias of  
+5V is required.
