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.
