The 142-0901-806 is an SMA jack-to-jack adapter used for in-series connection of two SMA plug connectors. It is constructed with a nickel-plated brass body, a gold-plated beryllium copper center contact, and a Teflon insulator, ensuring robust performance. This adapter operates over a frequency range of 0-18 GHz with a characteristic impedance of 50 Ohms. Key performance metrics include a maximum VSWR of 1.05 + 0.005(F) GHz and a high dielectric withstanding voltage of 1500 VRMS. Rated for a durability of 500 mating cycles and an operating temperature range of -65°C to 165°C, it is a reliable solution for test equipment, telecommunications, and other high-frequency systems.
