1 dB LSB 5-Bit Digital Attenuator SMT, 0.7 - 2.7 GHz

The HMC274QS16(E) is a broadband 5-bit positive control GaAs IC digital attenuator in a 16 lead QSOP plastic package. Covering 0.7 to 2.7 GHz the insertion loss is typically less than 2.3 dB. The attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB for a total attenuation of 31 dB. Accuracy is excellent at ± 0.5 dB typical with an IIP3 of up to +50 dBm. Five bit control voltage inputs, toggled between 0 and +3 to +5 volts, are used to select each attenuation state. A single Vdd bias of +3 to +5 volts applied through an external 5K Ohm resistor is required.
