QFN, 16pin, 3.0

mm x 3.0 mm

Key Features

• Broadband 5 – 3000 MHz frequency range

• 30 dB attenuation range

• +50 dBm Input IP3 (typical)

• +80 dBm Input IP2 (typical)

• Low Distortion: -80 dBc CSO and -75 dBc CTB for 132

channel 38 dBmV input

• High 1 dB compression point (> +30 dBm)

• Low supply current: 2 mA (typical)

• 3 V to 5 V power supply

• Linear in dB control characteristic

Product Overview

The RFSA3043 is a fully monolithic analog voltage-

controlled

attenuator

(VCA)

featuring

exceptional

linearity over a typical temperature compensated 30 dB

gain control range. It incorporates a revolutionary new

circuit architecture to solve a long-standing industry

problem: high IP3, high attenuation range, low DC

current,

broad

bandwidth

and

temperature

compensated linear in dB control voltage characteristic.

This voltage-controlled attenuator is controlled by a

single

positive

control

voltage

with

on-chip

DC

conditioning circuitry. The slope of the control voltage

versus gain is selectable. The RFSA3043 draws a very

low 2 mA current and is packaged in a small 3 mm x

3 mm QFN. This attenuator is matched to 75 Ω over its

rated control range and frequency with no external

matching components required.
