General Description
The HMC306MS10 & HMC306MS10E are general
purpose broadband 5-bit positive control GaAs IC
digital attenuators in 10 lead MSOP surface mount
plastic packages. Covering 0.7 to 3.8 GHz, the
insertion loss is typically less than 1.5 to 2.3 dB.
These attenuators’ 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 ± 0.2 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. A single Vdd bias of +3 to +5V ap-
plied through an external 5K Ohm resistor is required.
