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.
