Product Description Peregrine’s PE94302 is a high linearity, 6-bit UltraCMOS® RF digital step attenuator (DSA). This 50Ω RF DSA covers a 31.5 dB attenuation range in 0.5 dB steps. It provides both parallel and serial CMOS control interface. The PE94302 maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and power consumption. The PE94302 is optimized for commercial space applications. Single event latch-up (SEL) is physically impossible and single event upset (SEU) is better than 10/9 errors per bit/day. Fabricated in Peregrine’s UltraCMOS technology, a patented variation of silicon-on-insulator (SOI) technology on a sapphire substrate, the PE94302 offers excellent RF performance and intrinsic radiation tolerance.
