Product Specification
PE43404
75 ? RF Digital Attenuator
Product Description
The PE43404 is 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
4-bit, 15 dB, DC – 2.0 GHz
Features
? Attenuation: 1.0 dB steps to 15 dB
? Flexible parallel and serial programming
interfaces
single 3-volt supply and maintains high attenuation accuracy
?
Parallel latched or direct mode
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.
? High attenuation accuracy and linearity
over temperature and frequency
? Unique power-up state selection
? Very low power consumption
? Single-supply operation
? Positive CMOS control logic
? 75 ? impedance
? Packaged in a 20 Lead 4x4 mm QFN
