Product Description
RFMD’s RFSA2113 is a fully monolithic analog voltage controlled attenuator
(VCA) featuring exceptional linearity over a typical temperature compensated
30dB gain control range. The RFSA2113 features a wide bandwidth up to 18GHz.
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 polarity of the
control voltage versus gain is selectable. The RFSA2113 draws a very low 2mA
current. This attenuator is matched to 50Ω over its rated control range and
frequency with no external matching components required. Typical VCA’s in this
performance are based on compound semiconductor GaAs FET MMICs that
require 1 to 2 negative voltages for control. This game changing product
incorporates the complete solution in a small 3.2mm x 3.2mm MCM package
that reduces the footprint in area and simplifies the control aspects over
conventional compound semiconductor attenuator approaches.
