75 Ω Rf Digital Attenuator 5-bit, 31 Db, Dc - 4.0 Ghz Semiconductor Corp.

75 Rf Digital Attenuator 5-bit, 31 Db, Dc - 4.0 Ghz Semiconductor Corp.,The PE4308 is a high linearity, 5-bit RF Digital Step Attenuator (DSA) covering 31 dB attenuation range in 1dB steps, and is pin compatible with the PE430x series. 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 unique control Interface that allows the user to select an initial attenuation state at power-up. The PE4308 exhibits very low insertion loss and low power consumption. This functionality is delivered in a 4x4 mm QFN footprint. The PE4308 is manufactured on Peregrines 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.
