Product Overview

Qorvo's RFSA2023 is a fully monolithic analog voltage

control attenuator (VCA) featuring exceptional linearity

over 30dB adjustment range with on-chip temperature

compensation.

RFSA2023 incorporates a revolutionary new circuit

architecture. It solved the long-standing industry

problems of IP3, attenuation range, DC current,

bandwidth, and temperature compensation. RFSA2023

is also designed with linear in dB control characteristic.

There is no external analog supporting circuitry

required. This attenuator is controlled by a single

positive variable voltage with DC conditioning circuitry

also on-chip. The slope of the attenuation versus control

voltage is selectable. The RFSA2023 draws only 1mA

current. It is internally matched to 50

Ω and works quite

well over its rated ranges of control voltage and

frequency.

This game-changing product integrates the complete

solution into a small 3mm x 3mm QFN package. That

reduces the footprint by 20X in area and reduces the

DC power by 10X over the PIN diode approaches.
