SSMC connectors, also known as ultra-miniature threaded connectors, are a type of miniaturized coaxial connectors used in the RF field. SSMC connectors have many advantages. They are extremely compact in size, with a volume reduction of about one-third compared to SMC connectors, which can save up to 40% of space. They adopt a threaded connection mechanism, ensuring a stable and reliable connection and excellent vibration resistance. The working frequency range can meet the requirements of various high-frequency applications, with high signal transmission efficiency and low insertion loss, effectively ensuring signal quality. They are highly durable and can adapt to various harsh environmental conditions.
