Typical Applications
The HMC288MS8 is a broadband 3-bit positive con-
trol GaAs IC digital attenuator in an 8 lead MSOP
surface mount plastic package. Covering 0.7 to 3.7
GHz, the insertion loss is typically less than 1.2 to
1.8 dB. The attenuator bit values are 2 (LSB), 4,
and 8 dB for a total attenuation of 14 dB. Accuracy
is excellent at ± 0.3 dB typical with an IIP3 of up to
+51 dBm. Three bit control voltage inputs, toggled
between 0 and +3 to +5V, are used to select each
attenuation state at less than 50 uA each. A single
Vdd bias of +3 to +5V applied through an external
5K Ohm resistor is required while occupying less
than 14.8 mm2.
The HMC288MS8 is ideal for:
