Typical Applications
The HMC274QS16 is ideal for:
Cellular/PCS/3G Infrastructure
2.4 GHz ISM Radios
Wireless Data
The HMC274QS16 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 inser-
tion 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.
