Typical applications

The HMC273AMS10G(E) is a general purpose

broadband 5-Bit positive control GaAs IC digital

attenuator in a 10 lead MSOP plastic package.

Covering 0.7 to 3.8 GHz, the insertion loss is typically

less than 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 ±0.2 dB typical

with an IIP3 of up to +46 dBm. Five bit control vol-

tage 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.

The HMC273AMS10G(E) is ideal for:

• Cellular; UMTS/3G Infrastructure

• ISM, MMDS, WLAN, WiMAX

• Microwave Radio & VSAT

• Test Equipment and Sensors
