The FMAD1203 is an in-series RF adapter designed to connect SMA male to 2.92mm female interfaces. This 50-ohm adapter operates over a frequency range from DC to 26.5 GHz and maintains a low VSWR of 1.2:1 maximum. It is constructed with a passivated stainless steel body and features gold-plated beryllium copper contacts for durability and reliable signal transmission. Ideal for general-purpose testing and enabling between-series connections, its SMA connector is also mechanically compatible with commercial 3.5mm and 2.92mm (K) connectors.
