Product Specification

PE4305

50 Ω RF Digital Attenuator

5-bit, 15.5 dB, DC – 4.0 GHz

Product Description

Features

The PE4305 is a high linearity, 5-bit RF Digital Step Attenuator

(DSA) covering a 15.5 dB attenuation range in 0.5 dB steps,

and is pin compatible with the PE430x series. This 50-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

PE4305 exhibits very low insertion loss and low power

consumption. This functionality is delivered in a 4x4 mm QFN

footprint.

• Attenuation: 0.5 dB steps to 15.5 dB

• Flexible parallel and serial programming

interfaces

• Latched or direct mode

• Unique power-up state selection

• Positive CMOS control logic

• High attenuation accuracy and linearity

over temperature and frequency

• Very low power consumption

• Single-supply operation

The PE4305 is manufactured in Peregrine’s patented Ultra

Thin Silicon (UTSi®) CMOS process, offering the performance

of GaAs with the economy and integration of conventional

CMOS.

• 50 Ω impedance

• Pin compatible with PE430x series

• Packaged in a 20 Lead 4x4 mm QFN
