Product Description

This product is a high linearity, 6-bit RF Digital Step Attenuator

(DSA) covering a 31.5 dB attenuation range in 0.5 dB steps.

The Peregrine 50Ω RF DSA provides a parallel CMOS control

interface and it operates on 3-volt to 5-volt supply. It maintains

high attenuation accuracy over frequency and temperature and

exhibits very low insertion loss and low power consumption.

This Peregrine DSA is available in a 4x4 mm 24 lead QFN

footprint with an exposed ground paddle.

The PE4309 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.

4. Measurements made in a 50 ohm system (see Figure 4, Test Circuit Block Diagram). Resistors (R2, R3, R5, R6, R7) with a

value of 10K-ohm are used to decouple the RF path from the control inputs.
