The PE43404 is a high linearity, 4-bit RF Digital Step Attenuator (DSA) covering a 15 dB attenuation range in 1.0 dB steps. This 75-ohm RF DSA provides both parallel (latched or direct mode) and serial CMOS control interface, operates on a single 3-volt supply and maintains high attenuation accuracy over frequency and temperature. It also has a control interface that allows the user to select an initial attenuation state at power-up. The PE43404 exhibits very low insertion loss and low power consumption. This functionality is delivered in a 20-lead 4x4 mm QFN footprint.
