RFSA3043

75Ω Voltage Controlled Attenuator

5MHz to 3000MHz

Package: QFN, 16-pin,

3.0mm x 3.0mm

RFMD’s RFSA3043 is a fully monolithic analog voltage controlled

attenuator (VCA) featuring exceptional linearity over a typical temperature

compensated 30dB 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 2mA current and is

packaged in a small 3mm x 3mm QFN. This attenuator is matched to 75Ω

over its rated control range and frequency with no external matching

components required. Typical VCAs in this performance category have poor

inherent attenuation versus temperature and poor nonlinear attenuation

versus control voltage characteristics. To correct these short-comings, other

VCAs require extensive off chip analog support circuitry that consumes

valuable PCB area and additional DC power. This game changing product

incorporates the complete solution in a small 3mm x 3mm QFN package

that reduces the footprint 20x in area and reduces the DC power by 5x over

conventional PIN diode approaches.
