The HMC306MS10 is a broadband 5-bit positive control GaAs IC digital attenuator designed for the frequency range of 0.7 to 3.8 GHz. It has a typical insertion loss of less than 1.5 to 2.3 dB and a total attenuation of 15.5 dB. The attenuation accuracy is ±0.25 dB and it features a miniature package and low power consumption.
The HMC306MS10 is a broadband 5-bit positive control GaAs IC digital attenuator housed in a miniature 10-lead MSOP surface mount plastic package. It covers the frequency range of 0.7 to 3.8 GHz with an insertion loss typically less than 2.3 dB and provides attenuation steps from 0.5 dB up to a total of 15.5 dB.
The device features five bit control voltage inputs toggled between 0 and +3V to +5V, requiring a single Vdd bias applied through an external resistor. Key specifications include an input third-order intercept point (IIP3) of up to +52 dBm and switching times of 600 ns for turn-on/off operations.
