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 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 HMC307QS16G is an excellent alternative to the HMC235QS16G.
