Typical Applications
The HMC291 is a broadband 2 - bit positive control
GaAs IC digital attenuator in a 6 lead SOT26 sur-
face mount plastic package. Covering 0.7 to 4 GHz,
the insertion loss is typically less than 0.7 to 1.3 dB.
The attenuator bit values are 4 (LSB) and 8 dB for a
total attenuation of 12 dB. Accuracy is excellent at ±
0.2 dB typical with an IIP3 of up to +54 dBm. Two bit
control voltage inputs, toggled between 0 and +3 to
+5 volts, are used to select each attenuation state at
less than 50 uA each. A single Vdd bias of +3 to +5
volts applied through an external 5K Ohm resistor is
required.
The HMC291 is ideal for:
