Product Description

RFMD's RFSA3013 is a fully monolithic analog voltage controlled attenuator (VCA) featuring

exceptional linearity over a typical temperature compensated 30dB gain control range. It incor-

porates 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 RFSA3013 draws a very low 1mA current and is packaged

in a small 3mm x 3mm QFN. This attenuator is matched to 75 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 shortcomings, other VCAs require exten-

sive off chip analog support circuitry that consume 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 by 20X in area and reduces the DC power by 10X over con-

ventional PIN diode approaches.
