General Description
The HMC467LP3 is a broadband 2-bit GaAs IC
digital attenuator in a low cost leadless surface
mount package. Covering DC to 6.0 GHz, the
insertion loss is less than 0.7 dB typical. The
attenuator bit values are 2 (LSB) and 4 dB for a
total attenuation of 6 dB. Attenuation accuracy
is excellent at ± 0.2 dB typical step error with
an IIP3 of +50 dBm. Two control voltage inputs,
toggled between 0 and +5V, are used to select
each attenuation state. A single Vdd bias of +5V
is required.
