PE4306

www.DataSheet4U.com Product Specification PE4306 Product Description The PE4306 is a high linearity, 5-bit RF Digital Step Attenuator (DSA) covering a 31 dB attenuation range in 1dB steps, and is pin compatible with the PE430x series. This 50-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 unique control interface that allows the user to select an initial attenuation state at power-up. The PE4306 exhibits very low insertion loss and low power consumption. This functionality is delivered in a 4x4 mm QFN footprint. The PE4306 is manufactured in Peregrine’s patented Ultra Thin Silicon (UTSi®) CMOS process, offering the performance of GaAs with the economy and integration of conventional CMOS. Figure 1.
