Product Description
The PE4307 is a high linearity, 5-bit RF Digital Step Attenuator
(DSA) covering a 15.5 dB attenuation range in 0.5 dB steps.
The device is pin compatible with the PE430x series. This 75-
ohm RF DSA provides both parallel (latched or direct mode)
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 PE4307 exhibits very low insertion loss and low power
consumption. This functionality is delivered in a 4x4 mm QFN
footprint.
The PE4307 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.
