Typical Applications
The HMC274QS16 / HMC274QS16E is ideal for:
Cellular/PCS/3G Infrastructure
2.4 GHz ISM Radios
Wireless Data
The HMC274QS16 & HMC274QS16E are broadband
5-bit positive control GaAs IC digital attenuators in
16 lead QSOP plastic packages. 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.
