PE94302

50 Ω RF Digital Step Attenuator

For Rad-Hard Space Applications

6-bit, 31.5 dB, DC – 4.0 GHz

Product Description

The PE94302 is a high linearity, 6-bit UltraCMOS™ RF Digital

Step Attenuator (DSA) specifically optimized for rad-hard space

applications. This 50-ohm RF DSA covers a 31.5 dB

attenuation range in 0.5 dB steps. It provides both parallel and

serial CMOS control interface which operate on a single 3-volt

supply. It also has a unique control interface that allows the

user to select an initial attenuation state at power-up. The PE

94302 maintains high attenuation accuracy over frequency and

temperature and exhibits very low insertion loss and power

consumption.

Features

• Attenuation: 0.5 dB steps to 31.5 dB

• Flexible parallel and serial programming

interfaces

• 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

• 50 Ω impedance

The PE94302 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.
