SMA
The SMA "SubMiniature A" connector series is one of the most commonly used RF connector due to its durability and performance. SMA series has a 1/4 - 36 UNS threaded coupling and can operate up to 18 GHz when using semi-flex or semi-rigid cable types.
MMCX
The Micro-Miniature CoaXial (MMCX) is a miniaturised version of the MCX RF connector and features snap-on coupling. The series is only 2.4 mm in diameter, ideal for lightweight and space-limited applications. MMCX has the same inner and outer contact interface dimensions as SMB but 45% smaller. The connector utilises a slot-less design to minimise RF leakage, and has been standardised under IEC 61169-52 specification.
