Generꢀl description
The HMC306AMS10
&
HMC306AMS10E are
general purpose broadband 5-bit positive control
GaAs IC digital attenuators in 10 lead MSOP surface
mount plastic packages. Covering 0.7 to 3.8 GHz,
the insertion loss is typically less than 1.5 to 2.3 dB.
These attenuators’ bit values are 0.5 (LSB), 1, 2, 4 and
8 dB for a total attenuation of 15.5 dB. Attenuation
accuracy is excellent at 0.2 dB typical with an IIP3
of up to +52 dBm. Five bit control voltage inputs,
toggled between 0 and +3 to +5V, are used to select
each attenuation state. A single Vdd bias of +3 to +5V
applied through an external 5K Ohm resistor is requ-
ired.
