Features and Benefits
- RoHS compliant product
- 4 dB LSB steps to 12 dB
- Single positive control per bit, 0/+3V or +5V
- Typical step error : ±0.3 dB
- Miniature SOT 26 package: 9 mm2
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 required.
