Product Description
The PE4302 is a high linearity, 6-bit RF Digital Step Attenuator (DSA) covering a 31.5 dB attenuation range in 0.5 dB steps. This 50-ohm RF DSA provides both parallel 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 PE4302 exhibits very low insertion loss and low power consumption. This functionality is delivered in a 4x4 mm QFN footprint.
The PE4302 is manufactured on Peregrine’s UltraCMOS™ process, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, offering the performance of GaAs with the economy and integration of conventional CMOS.
