HMC273AMS10GETR General Description

The HMC273AMS10G(E) is a general purposebroadband 5-Bit positive control GaAs IC digitalattenuator in a 10 lead MSOP plastic package.Covering 0.7 to 3.8 GHz, the insertion loss is typicallyless than 3 dB. The attenuator bit values are1 (LSB), 2, 4, 8, and 16 dB for a total attenuationof 31 dB. Accuracy is excellent at ±0.2 dB typicalwith an IIP3 of up to +46 dBm. Five bit control voltageinputs, toggled between 0 and +3 to +5 volts, areused to select each attenuation state. A single Vddbias of +3 to +5 volts applied through an external5K Ohm resistor is required.
