ENDCE W Product Description
The PE43670 is a high linearity, 7-bit RF Digital Step Attenuator (DSA). This highly versatile DSA covers a 31.75
A d B attenuation range in 0.25 d B steps. The Peregrine 50Ω RF DSA provides a parallel or serial-addressable L CMOS control interface. It maintains high attenuation accuracy over frequency and temperature and exhibits very low insertion loss and low power consumption. Performance does not...
