Typical Applications
The HMC291 & HMC291E are general purpose
broadband 2-bit positive control GaAs IC digital
attenuators in 6 lead SOT26 surface mount plastic
packages. 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 & HMC291E are ideal for:
