General Description

The HMC306MS10 is a broadband 5-bit posi­tive control GaAs IC digital attenuator in a 10

SINGLE POSITIVE CONTROL PER BIT
+/- 0.25 dB TYPICAL BIT ERROR
MINIATURE MSOP-10 PACKAGE: 14.8 mm²

lead MSOP surface mount plastic package.
Covering 0.7 to 4 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 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 5KΩ resistor
is required. The HMC306MS10 is ideal for
cellular, PCS, ISM, MMDS, and WLL applica­tions while occupying less than 14.8 mm².
