General Description
The HMC273MS10G is a broadband 5 - bit positive
control GaAs IC digital attenuator in a 10 lead MSOP
plastic package. Covering 0.7 to 3.7 GHz, the inser-
tion loss is typically less than 2 dB. The attenuator
bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total
attenuation of 31 dB. Accuracy is excellent at 鹵 0.5
dB typical with an IIP3 of up to +48 dBm. Five bit
control voltage inputs, toggled between 0 and +3 to
+5 volts, are used to select each attenuation state.
A single Vdd bias of +3 to +5 volts applied through
an external 5K Ohm resistor is required.
