•MCX series: Connectors in the MCX (Micro Coaxial) series feature a snap-on coupling mechanism for fast and convenient connection and are intended for operation from DC to 6 GHz (Figure 8). These connectors are compatible with IEC 61169-36, “Radio- frequency connectors - Part 36: Microminiature r.f. connectors with snap-on coupling - Characteristic impedance 50 Ω (Type MCX)”. The 60612202111308 is a surface mount, edge launch jack in the MCX series, suitable for boards up to 1.6 mm thick. It has a VSWR of 1.3 and insertion loss of 0.25 dB over that range and is rated for 500 cycles. • MMCX series: These connectors are approximately 30% smaller compared to the MCX connectors and are suitable for applications with ultra-small design requirements (Figure 10). They have a snap-on coupling mechanism for fast and easy connection and also meet IEC 61169-36.
