RoHS Compliance: No
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.
