Product Description
The PE94302 is a high linearity, 6-bit UltraCMOSRF 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.
