Typical Applications
The HMC307QS16G(E) are broadband 5-bit GaAs
IC digital attenuators in 16 lead QSOP grounded
base surface mount plastic packages. 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.
The HMC307QS16G(E) is ideal for:
