The PE94302 is a high linearity, 6-bit UltraCMOSTM 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.
