Product Specification
PE4307
75 ? RF Digital Attenuator
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.
