Product Summary
The HMC274 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. 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. The applications of the HMC274 include: Cellular/PCS/3G Infrastructure, 2.4 GHz ISM Radios, Wireless Data.
Parametrics
HMC274 absolute maximum ratings: (1)Control Voltage (V1 - V5): Vdd + 0.5 Vdc; (2)Bias Voltage (Vdd): +8.0 Vdc; (3)Storage Temperature: -65 to +150 ℃; (4)Operating Temperature: -40 to +85 ℃; (5)RF Input Power (0.7 - 2.7 GHz): +30 dBm.
Features
