HMC290 290E / v01.0605 2 dB LSB GaAs MMIC 2-BIT DIGITAL ATTENUATOR, 0.7 - 4.0 GHz 5 Typical Applications Features The HMC290 / HMC290E is ideal for: 2 dB LSB Steps to 6 dB T M • Cellular Single Positive Control Per BIT S • PCS, ISM, MMDS ±0.2 dB Typical Bit Error - • WLL Handset & BaseStation Miniature SOT 26 Package: 9 mm2 L A T I G Functional Diagram General Description I D The HMC290 & HMC290E are broadband 2 - bit positive control GaAs IC digital attenuators in 6 lead - S SOT26 surface mount plastic packages. Covering 0.7 R to 4 GHz, the insertion loss is typically less than 0.7 O dB. The attenuator bit values are 2 (LSB) and 4 dB for T a total attenuation of 6 dB. Accuracy is excellent at ± A 0.2 dB typical with an IIP3 of up to +52 dBm. Two bit U control voltage inputs, toggled between 0 and +3 to N +5 volts, are used to select each attenuation state at E less than 50 uA each. A single Vdd bias of +3 to +5 T volts applied through an external 5K Ohm resistor is T A required. Occupying less than 9 mm2, this is the small- est 2 - bit digital attenuator available.
