The HMC307QS16G / 307QS16GE is a 5-bit digital attenuator from Hittite Microwave Corporation. It has a 1dB LSB step and a 31dB attenuation range with an accuracy of ±0.5dB.
The HMC307QS16G and HMC307QS16GE are broadband 5-bit GaAs IC digital attenuators housed in a 16-lead QSOP grounded base surface mount plastic package. These devices cover a frequency range from DC to 4 GHz, offering an insertion loss of less than 2 dB typical. The attenuator provides 1 dB LSB steps to a total attenuation of 31 dB, with an attenuation accuracy of ±0.5 dB typical and 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.
