Functional Diagram

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.
