General Description
The HMC306MS10 is a broadband 5-bit positive
control GaAs IC digital attenuator in a 10 lead
MSOP surface mount plastic package. Covering
0.7 to 3.8 GHz, the insertion loss is typically less
than 1.5 to 2.3 dB. The attenuator bit values are
0.5 (LSB), 1, 2, 4 and 8 dB for a total attenuation
of 15.5 dB. Attenuation accuracy is excellent at ±
0.25 dB typical with an IIP3 of up to +52 dBm. Five
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 single Vdd bias of +3 to
+5V applied through an external 5K Ohm resistor
is required. The HMC306MS10 occupies less than
14.8 mm².
