Functional Diagram
General Description
The HMC291SE is a general purpose broadband
2-bit positive control silicon IC digital attenuator in
6 lead SOT26 surface mount plastic package. The
insertion loss is typically in between 0.4 dB - 1 dB
through operating frequency range. The attenuator
bit values are 4 (LSB) and 8 dB for a total attenuation
of 12 dB. State error is excellent at ± 0.4 dB typical
with an IIP3 of up to 57 dBm. Two bit control voltage
inputs, toggled between 0V and +3V or +5V, are used
to select each attenuation state at less than 25 µA
each. A single VDD supply voltage of +3V to +5V
applied through an external 4.7K Ohm resistor is
