SM4216 is a right-angle SMA female to N male adapter from Fairview Microwave designed to enable connections between two incompatible connector types in RF and microwave applications. The adapter operates across a frequency range from DC to 4 GHz with excellent VSWR performance of 1.2:1 maximum and an impedance of 50 ohms. It features a low-profile right-angle body geometry that facilitates easier connections in tight spaces, with mechanical compatibility to 3.5mm and 2.92mm (K) connectors. The adapter is constructed with gold-plated beryllium copper contacts (1.3 µm minimum plating) and PTFE insulation, rated for 100 mating cycles on each connector and an operating voltage of 335 Vrms AC. This adapter is ideal for general-purpose RF testing, between-series connections, and as a connector saver to protect expensive equipment from wear during frequent connect/disconnect cycles.
