Qorvo'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 50 ohm 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.

This product is available as an X-Microwave Block (X-MWblock) for evaluation.
X-MWblocks are RF and microwave "drop-in" components that can be used individually for prototyping or in production assemblies. X-MWblocks are easy to test, integrate, align, and configure to 60 GHz and beyond. No messy sweat soldering or silver epoxy processes are required. X-MWblocks are highly characterized with S-parameter models and connect with a patented solder-less interconnect technology.
