Components & Connectors

Miniature cable assemblies from Amphenol RF have been supplemented with the introduction of SMA to AMC configurations on micro-coax cable types, capable of Wi-Fi 6 performance. 

The additional SMA to AMC configurations are on 1.13 and 1.32mm micro-coax cables. The configurations offer more efficient bandwidth sharing and RF performance up to 9.0GHz. According to Amphenol, the versatile SMA connector is coupled with the small footprint AMC connector, making the assemblies suitable for IoT, antenna and Wi-Fi 6 applications.

SMA connectors are a popular choice for designs that require vibration resistant capabilities because the threaded coupling mechanism ensures a secure connection. The front mount SMA bulkhead jacks are constructed with gold plated brass bodies and gold plated phosphor bronze contacts. The AMC connectors are compatible with the industry standard U.FL for miniature connectors. In addition to saving space, the AMC connectors introduced by Amphenol RF have a user friendly tactile lock which guarantees a reliable connection, says the company. These right-angle connectors are engineered with either gold plated black PBT (polybutylene terephthalate) or silver plated phosphor bronze bodies and gold plated phosphor bronze contact. Flexible micro-coax cables complete this assembly design; they are also designed for applications where space is limited. The 1.32mm version is also double shielded to ensure low signal loss.

These 50 Ohm SMA to AMC cable assemblies join Amphenol RF’s collection of existing miniature cable assemblies. They feature an extended frequency range that allows them to support Wi-Fi 6 and Wi-Fi 6E, high-efficiency Wi-Fi designs. This type of Wi-Fi is typically used in dense environments and employs advanced antenna technology which allows for more simultaneous communications and improved speeds.

Amphenol RF is a manufacturer of coaxial connectors for use in radio frequency (RF), microwave, and data transmission system applications. Headquartered in Danbury, Connecticut, USA, Amphenol RF has sales, marketing and manufacturing locations in North America, Asia and Europe. Standard products include RF connectors, coaxial adapters and RF cable assemblies. Custom engineered products include multi-port ganged interconnect, blind mate and hybrid mixed-signal solutions.

Designed and manufactured at Link Microtek’s UK facility, the AMCORJD-3 is a three-channel rotary joint for X-band radar systems. It joins the company’s existing range of microwave rotary joints. One of the three X-band channels is used for transmit and the others for receive signals in radar systems for coastal/border surveillance or critical infrastructure protection. 

The AMCORJD-3 enables microwave signals to be fed to or from a compact radar antenna rotating continuously at speeds in excess of 60rpm and typically exposed to harsh environmental conditions such as wind, rain and salt spray. It was also designed to fit in the same space as the company’s earlier, two-channel version.

Both channels cover the frequency range 8.5 to 9.5GHz and can handle average microwave power in excess of 50W and peak powers of over 200W. In terms of microwave performance, maximum insertion loss is only 1.2dB, maximum VSWR (voltage standing wave ratio) is 1.5:1 and isolation is 80dB.

To satisfy requirements for long life and continuous operation, the robust rotary joint uses a non-contacting design, so the only parts subject to wear are the bearings. The AMCORJD-3 is fabricated from lightweight aluminium with a Surtec finish and incorporates IP65 sealing to protect it from the ingress of moisture and dust. There are N-type connectors on the rotating side and SMA connectors on the fixed side. The rotary joint has overall dimensions of 84 x 150mm, excluding the connectors and bulkhead mounting flange. Other rotary-joint configurations and sizes can be supplied on request and customised to suit specific radar antenna requirements.

At next week’s DesignCon 2022, Yamaichi and JAE will show the jointly developed high speed jumper able interconnect which supports the 112Gbits per second PAM4 signal. 

It has been developed to meet the need for increased data transmission speeds for network equipment such as the routers and switches as the 5G network expands and the industry moves towards 6G technology. To fulfill this market demand, said Yamaichi, it has teamed up with JAE to developed the interconnect, combining both company’s design expertise.

As requirements for data transmission speed reach upper limits of existing PCB technologies, it is becoming more difficult to realise constant and reliable data transmission performance. To solve this problem, the two companies have jointly developed a jumper cable interconnect product which can perform stable data transmission at 112Gbits per second PAM4 signalling.

The interconnect has been designed with a compact connector in order to fit in high-density designs. It can be used for direct jumper cabling from the front panel pluggable I/O to host chip, or for internal chip to chip connection.

Yamaichi supplies high speed connectors for data networking market and JAE specialises in connector and cable harness products for a range of market segments including 5G data networking market. 

The high speed jumper able interconnect will be demonstrated at the Yamaichi booth #960) at DesignCon2022 in Santa Clara, California, USA from 5 to 7 April.
