HMC288MS8

ATTENUATORS - SMT 5 5 - 34 HMC288MS8 / 288MS8E v01.0705 2 dB LSB GaAs MMIC 3-BIT DIGITAL ATTENUATOR, 0.7 - 3.7 GHz Typical Applications Features The HMC288MS8 / HMC288MS8E is ideal for: 2 dB LSB Steps to 14 dB Cellular Single Positive Control Per BIT PCS, ISM, MMDS Monotonic: ±03 dB Bit Error Typical WLL applications LETE Functional Diagram Miniature MSOP-8 Package, 14.8mm2 General Description The HMC288MS8 & HMC288MS8E are broadband 3-bit positive control GaAs IC digital attenuators in 8 lead MSOP surface mount plastic packages. Covering 0.7 to 3.7 GHz, the insertion loss is typically less than 1.2 to 1.8 dB. The attenuator bit values are 2 (LSB), 4, and 8 dB for a total attenuation of 14 dB. Accuracy is excellent at ± 0.3 dB typical with an IIP3 of up to +51 dBm. Three bit control voltage inputs, toggled between 0 and +3 to +5V, are used to select each attenuation state at less than 50 uA each. A single Vdd bias of +3 to +5V applied through an external 5K Ohm resistor is required while occupying less than 14.8 mm2.
