PE43404
75-ohm, 4-bit RF Digital Attenuator
1.0 dB steps to 15 dB, 1 – 2000 MHz
RoHS Compliant
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 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 20-lead 4x4 mm QFN footprint.
