HMC290E Datasheet | Analog Devices

Features 2 d B LSB Steps to 6 d B Single Positive Control Per BIT ±0.2 d B Typical Bit Error Miniature SOT 26 Package: 9 mm2 General Description The HMC290 & HMC290E are 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 d B. The attenuator bit values are 2 (LSB) and 4 d B for a total attenuation of 6 d B. Accuracy is excellent at ± 0.2 d B typical with an IIP3 of up to +52 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. Occupying less than 9 mm2, this is the smallest 2 - bit digital attenuator available. - 36 Electrical Specifications, TA = +25° C, Vdd = +3V to +5V & Vctl = 0/Vdd (Unless Otherwise Stated) Parameter Frequency Min.
