Monotonic: ±0.3 dB Bit Error Typical

Miniature MSOP-8 Package, 14.8mm²

The HMC288MS8(E) is a broadband 3-bit positive control GaAs IC digital attenuator in an 8 lead MSOP surface mount plastic package. 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.
