HMC291SE v05.1216 ATTENUATORS - ANALOG - SMT 4 dB LSB SILICON 2-BIT POSITIVE CONTROL DIGITAL ATTENUATOR, 0.7 - 4.0 GHz Typical Applications Features The HMC291SE is ideal for: RoHS Compliant Product * Cellular 4 dB LSB Steps to 12 dB * PCS, ISM, MMDS Single Positive Control Per Bit, 0/+3V or +5V * WLL Handset & Base Station Typical Step Error : 0.3 dB Miniature SOT 26 Package: 9 mm2 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 A each. A single VDD supply voltage of +3V to +5V applied through an external 4.7K Ohm resistor is required.
