Product Specification
PE4302
Product Description
The PE4302 is a high linearity, 6-bit RF Digital Step Attenuator
鈥淒SA鈥?covering a 31.5 dB attenuation range in 0.5 dB steps.
This 50-ohm RF DSA provides both parallel and serial CMOS
control interface operates on a single 3-volt supply and
maintains high attenuation accuracy over frequency and
temperature. It also has a unique control interface that allows
the user to select an initial attenuation state at power-up. The
PE4302 exhibits very low insertion loss and low power
consumption. This functionality is delivered in a 4x4mm QFN
footprint.
The PE4302 is manufactured in Peregrine鈥檚 patented Ultra
Thin Silicon (UTSi廬) CMOS process, offering the performance
of GaAs with the economy and integration of conventional
CMOS.
