General Description
The HMC307QS16G & HMC307QS16GE are broad-
band 5-bit GaAs IC digital attenuators in 16 lead
QSOP grounded base surface mount plastic pack-
ages. 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 accuracy 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 attenuation 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.
