wwTwh.deataPshEe4et344u.0co4mis a high linearity, 4-bit RF Digital Step
Attenuator (DSA) covering a 15 dB attenuation range in 1.0 dB
steps. 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 PE43404 exhibits very low insertion
loss and low power consumption. This functionality is delivered
in a 4x4 mm QFN footprint.
The PE43404 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.
