Product Description
RFMDâs 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 50⦠over its rated control range and
frequency with no external matching components required. Typical VCAâs 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.
