General Description
The HMC472LP4 is a broadband 6-bit GaAs IC
digital attenuator in a low cost leadless surface
mount package. This single positive control line
per bit digital attenuator incorporates off chip
AC ground capacitors for near DC operation,
making it suitable for a wide variety of RF and IF
applications. Covering DC to 3.0 GHz, the
insertion loss is less than 2.0 dB typical. The
attenuator bit values are 0.5 (LSB), 1, 2, 4, 8,
and 16 dB for a total attenuation of 31.5 dB.
Attenuation accuracy is excellent at ± 0.5 dB
typical step error with an IIP3 of +45 dBm. Six
TTL/CMOS control inputs are used to select
each attenuation state. A single Vdd bias of +5V
is required.
