5G Solutions | Low PIM Connectors: 7/16, N-Type

5G is currently most popular word in the wireless infrastructure. 5G features high speeds, low latency and reliability that can be transformed to enable the transportation infrastructure, automation across urban and other industries.

In the meantime, due to the new frequency use for the modern base stations, the use of more sensitive receivers and higher transmitter power levels, PIM issues start to be a potential problem for cellular network services.

Chin Nan provides low PIM RF connectors, including N-Type | TNC | SMA | MCX | SMP | SMPM | 7/16 connector series, as well as cable assemblies and adapters. Here we are going to introduce our low PIM products lines: 7/16 and N-type, which are the two most common interfaces used in low PIM application.

PIM is a significant issue for cellular network operators, such as 4G and 5G LTE, they would like to maximize their networks' reliability, data transmission rate, capacity and revenue of investment.

It is important to have deep understanding of the issue and stick to the complete low PIM solutions. Let’s take low PIM antennas for example. Low PIM RF splitters and relevant cables, connectors and other passive component help you avoid costly requirements of upgrading relevant components and ensure the PIM won't interrupt the signal transmit.

In general sense, nonlinear mixing causes the generation of PIM, such as connectors, cables and antenna in the passive device.   The more nonlinearity exists, the more severe effects cause PIM. Chin Nan designs and improves the connectors through lowering and eliminating the cause of PIM as follows.

Lack of techniques, manufacturing defects resulting in loosely done connectors, and cold solder joint create PIM.

With the experienced design and development ability, Chin Nan has a strict manufacturing process to control the tolerances when machining and utilize the inspection tools to measure the dimensions from the machining to shipment to decrease the possibility of damaged connectors, cold solder or cracked solder joint.

Our design and products are made compliant to international standard interface. We also provide our employees proper training and establish complete assembly process. These allow Chin Nan to reduce defective in production.

The use of ferromagnetic materials, such as nickel or steel, generates PIM resulting from the nonlinear voltage to the current, especially at the high power level. Therefore, Chin Nan uses brass and copper alloys, which is regarded as linear materials, to make low PIM connectors.

For plating, we apply non-magnetic plating like sliver or white bronze specifically to reduce contact junction resistance. The point is to have proper thickness of plating for the smooth current travel by reducing the effects from the surface depth at the same time.

The problems of age, oxidation, corrosion, dirt and rust among others, and any kind of interruption on the passive devices are other major factors of PIM. Chin Nan applies the complete process including careful cleaning, proper assembly, good environmental protection and proper connector torque to minimize PIM.

7/16 Connectors are high performance, robust and stable connectors. They are designed for minimize PIM specifically.

7/16 features high frequency, low-intermodulation and low return loss, high power handing. 7/16 is designed with waterproof and anti-vibration specifications, so it is able to reduce signal interference from PIM and suitable for outdoor applications, especially for base stations, antenna and wireless communication systems.
