Product Specification
PE4306
50 ? RF Digital Attenuator
Product Description
The PE4306 is a high linearity, 5-bit RF Digital Step Attenuator
(DSA) covering a 31 dB attenuation range in 1dB steps, and is
pin compatible with the PE430x series. This 50-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
PE4306 exhibits very low insertion loss and low power
consumption. This functionality is delivered in a 4x4 mm QFN
footprint.
The PE4306 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.
