HMC274QS16 / 274QS16E
1 dB LSB GaAs IC 5-BIT DIGITAL
ATTENUATOR, 0.7 - 2.7 GHz
v01.0505
General Description
Features
Functional Diagram
1 dB LSB Steps to 31 dB
Single Positive Control (+3 to +5V) Per Bit
±0.5 dB Typical Bit Error
Small QSOP16 Plastic Package
Included in the HMC-DK004 Designer’s Kit
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.
