General Description
The HMC307QS16G is a broadband 5-bit GaAs IC
digital attenuator in a 16 lead QSOP grounded base
surface mount plastic package. Covering DC to 4
GHz, the insertion loss is less then 2 dB typical. The
attenuator bit values are 1 (LSB), 2, 4, 8, and 16 dB
for a total attenuation of 31 dB. Attenuation accu-
racy is excellent at ± 0.5 dB typical with an IIP3 of up
to +44 dBm. Five bit control voltage inputs, toggled
between 0 and -5V, are used to select each attenua-
tion state at less than 50 uA each. A single Vee bias
of -5V allows operation down to DC. This product is
an excellent alternative to the HMC235QS16G.
