Qorvo's RFSA2013 is a fully monolithic analog voltage controlled attenuator (VCA) featuring exceptional linearity over a minimum temperature compensated 30dB gain control range. 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 of the control voltage versus gain is selectable. The RFSA2013 draws a very low 1mA current and is packaged in a small 3mm x 3mm QFN. 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 category have poor inherent attenuation versus temperature and poor nonlinear attenuation versus control voltage characteristics. To correct these shortcomings, other VCA's require extensive off chip analog support circuitry that consume valuable PCB area and additional DC power. This game changing product incorporates the complete solution in a small 3mm x 3mm QFN package that reduces the footprint by 20X in area and reduces the DC power by 10X over conventional PIN diode approaches.

X-Microwave Design System
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.
