General Description
The HMC468LP3 is a broadband 3-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 1 dB typical up to 4
GHz. The attenuator bit values are 1 (LSB), 2 and
4 dB for a total attenuation of 7 dB. Attenuation
accuracy is excellent at ± 0.4 dB typical step error
with an IIP3 of +50 dBm. Three control voltage
inputs, toggled between 0 and +5V, are used to
select each attenuation state. A single Vdd bias
of +5V is required.
