The ERA-21SM+ is a surface-mount voltage-variable attenuator (VVA) produced by Mini-Circuits. It is designed for a wide range of applications including automated test equipment, signal leveling, and power control in RF communication systems.
The ERA-21SM+ typically comes in a small package suitable for surface-mount technology but does not have a standard "pin count" as it is not a traditional integrated circuit with pins. Instead, it features solder pads for mounting on a circuit board. It controls attenuation via a control voltage, providing precise and repeatable attenuation levels over a specified frequency range.
To determine exact solder pad connections and control functionality, it is recommended to consult the manufacturer's datasheet for detailed technical specifications, pin configurations, and functional descriptions.

The ERA-21SM+ is manufactured by Mini-Circuits, a company known for producing electronic components. Mini-Circuits specializes in designing, manufacturing, and distributing RF, IF, and microwave signal processing products.
