Typical Applications
The HMC288MS8 & HMC288MS8E are broadband
3-bit positive control GaAs IC digital attenuators in 8
lead MSOP surface mount plastic packages. Cover-
ing 0.7 to 3.7 GHz, the insertion loss is typically less
than 1.2
to 1.8 dB. The attenuator bit values are 2
(LSB), 4, and 8 dB for a total attenuation of 14 dB.
Accuracy is excellent at ± 0.3 dB typical with an
IIP3 of up to +51 dBm. Three bit control voltage inputs,
toggled between 0 and +3 to +5V, are used to select
each attenuation state at less than 50 uA each. A sin-
gle Vdd bias of +3 to +5V applied through an external
5K Ohm resistor is required while occupying less than
14.8 mm2.
The HMC288MS8 / HMC288MS8E is ideal for:
