Ultraminiature

Amphenol RF’s ultraminiature connectors deliver high-performance RF solutions in the smallest possible footprint, enabling reliable connectivity in today’s most compact electronic designs. With secure snap-on mating and low-profile construction, these interconnects provide both space efficiency and robust performance from DC to 6 GHz.


The AMC, AMC4 and AMMC ultraminiature series are engineered to meet the growing demand for miniaturization in portable and space-constrained devices. Designed with 50 ohm impedance and snap-on coupling, these connectors ensure easy installation while maintaining stable electrical performance. Their small board footprint and ultra-low profile make them ideal for high-density PCB layouts, offering the reliability and durability required for applications where space savings cannot come at the expense of signal integrity.

Ultraminiature RF connectors are widely deployed in RFID systems, GPS modules, Bluetooth devices and remote measuring equipment, where compact design and secure connectivity are essential. They are also integral to consumer electronics such as notebook computers, handhelds and other portable devices, supporting seamless wireless communication in lightweight, mobile platforms. By combining ease of use, space efficiency and compatibility with industry-standard solutions, Amphenol RF’s ultraminiature connectors deliver dependable performance for next-generation technologies.
