PE94302
Product Description
The PE94302 is a high linearity, 6-bit UltraCMOS RF Digital Step Attenuator (DSA) specifically optimized for rad-hard space applications. This 50-ohm RF DSA covers a 31.5 dB attenuation range in 0.5 dB steps. It provides both parallel and serial CMOS control interface. The PE 94302 maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and power consumption. The PE94302 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. 50 RF Digital Step Attenuator For Rad-Hard Space Applications 6-bit, 31.5 dB, DC – 4.0 GHz Features Attenuation: 0.5 dB steps to 31.5 dB
