Product Specification
PE4304
75 ? RF Digital Attenuator
Product Description
The PE4304 is a 75-ohm high-linearity, 6-bit RF Digital Step
Attenuator (DSA) covering a 31.5 dB attenuation range in 0.5
dB steps. The PE4304 provides both a 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 PE4304 exhibits very low insertion loss
and low power consumption. This functionality is delivered in a
4x4 mm QFN footprint.
The PE4304 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.
