The HMC307QS16G is a broadband 5-bit GaAs IC digital attenuator suitable for the DC to 4 GHz frequency range. It has an insertion loss of less than 2 dB and an attenuation range of 1 to 31 dB. The attenuation accuracy is ±0.5 dB, and the control voltage inputs are 0 and -5V.
The HMC307QS16G is a broadband 5-bit GaAs IC digital attenuator in a 16 lead QSOP grounded base surface mount plastic package. It covers the frequency range of DC to 4 GHz, offering an insertion loss of less than 2 dB typical and a total attenuation of 31 dB with 1 dB LSB steps.
The device features excellent attenuation accuracy of +/- 0.5 dB typical and an IIP3 of up to +44 dBm. It utilizes five bit control voltage inputs toggled between 0 and -5V, requiring a single Vee bias of -5V for operation down to DC.
