RFSA2113 Wide Bandwidth Voltage Controlled Attenuator Product Description The 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. This VCA incorporates a revolutionary new circuit architecture to solve a long standing industry problem: high IP3, high attenuation range, low DC current, broad 16 Pin, 3.2mm x 3.2mm x 1.175mm SMT Package bandwidth and temperature compensated linear in dB control voltage characteristic. Product Features The RFSA2113 attenuation level is set by a single positive Patented Circuit Architecture control voltage with on chip DC conditioning circuitry. The Broadband 50MHz to 18,000MHz Frequency Range slope polarity of the control voltage versus gain is 30dB Attenuation Range selectable. The RFSA2113 draws a very low 2mA current. This attenuator is matched to 50 over its rated control +45dBm IIP3 Typical range and frequency with no external matching +75dBm IIP2 Typical components required.
