Product Description
RFMD's RFSA2013 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 RFSA2013 draws a very low 1mA current and is packaged
in a small 3mm x 3mm QFN. This attenuator is matched to 50 over its rated control range and
frequency with no external matching components required. Typical VCA's in this performance
category have poor inherent attenuation versus temperature and poor nonlinear attenuation
versus control voltage characteristics. To correct these shortcomings, other VCA's 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.
