Features Ro HS pliant Product 4 d B LSB Steps to 12 d B Single Positive Control Per BIT, 0/+3V Typical Bit Error : ±0.2 d B Miniature SOT 26 Package: 9 mm2 Included in the HMC-DK004 Designer’s Kit Functional Diagram General Description The HMC291 & HMC291E are general purpose broadband 2-bit positive control Ga As 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 d B. The attenuator bit values are 4 (LSB) and 8 d B for a total attenuation of 12 d B. Accuracy is excellent at ± 0.2 d B typical with an IIP3 of up to +54 d Bm. Two bit control voltage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state at less than 50 u A each. A single Vdd bias of +3 to +5 volts applied through an external 5K Ohm resistor is required. Electrical Specifications, TA = +25° C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated) Insertion Loss Parameter Attenuation Range Return Loss (RF1 & RF2, All Atten.
