PE43404MLI-Z Datasheet, PDF (1/11 Pages) Peregrine Semiconductor – 75 Ω RF Digital Attenuator 4-bit, 15 dB, DC – 2.0 GHz

Product Specification
PE43404
Product Description
75 Ω RF Digital Attenuator
4-bit, 15 dB, DC – 2.0 GHz
The PE43404 is a high linearity, 4-bit RF Digital Step
Features
Attenuator (DSA) covering a 15 dB attenuation range in 1.0 dB
 Attenuation: 1.0 dB steps to 15 dB
steps. This 75-ohm RF DSA provides both parallel (latched or
 Flexible parallel and serial programming
direct mode) and serial CMOS control interface, operates on a
interfaces
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
E _{in a 4x4 mm QFN footprint.}
The PE43404 is manufactured on Peregrine’s UltraCMOS™
process, a patented variation of silicon-on-insulator (SOI)
T _{4 technology on a sapphire substrate, offering the performance}
1 ^{of GaAs with the economy and integration of conventional}
CMOS.
