Why Select I-PEX RF Connectors?

---

1) Industry Standard Connector

Current Standards

I-PEX MHF^® Series Connectors are standard components in a wide array of wireless devices including : smartphones, tablets, notebook M.2 and M2M modules, automotive infotainment systems, and more. As the Internet of Things (IoT) deployment accelerates, the MHF^® Series will play an increasing role in global wireless connectivity. With MHF^® connector shipments in excess of 25 billion units, I-PEX has consistently provided a robust, reliable and cost-effective solution for wireless design.

2) Variety of Options

2-1) RF Coaxial cable size variety

I-PEX offers a wide variety of MHF^® options to fit insertion loss and VSWR requirements. This selection offers flexibility in enabling wireless connectivity within a system. Depending on MHF^® type, coax outer diameters range from 0.48 mm (MHF^® 5) to 3.0 mm (MHF^®-TI). Typical insertion loss values by coax type and harness length, and minimum bend radius can be found below. 

Harness Length (mm) vs Insertion Loss (S21) : 2.4 GHz, 5.8 GHz, 9.0 GHz, 12 GHz, 15 GHz

Please refer to the product matrix file for cable insertion loss data at other frequencies.

 

 

2-2) Mated height and pad layout

I-PEX's MHF Series has a selection of mated height profiles that can fit in various designs. From small form factors like phones and tablets to notebooks to robust solutions for shock and vibration environments. In addition to the flexibility of mated heights, the MHF^® Series has several pad layouts design engineers can choose.

 

2-3) Mechanical lock

 

 

2-4) Ground clip and clamp

 

 

Electric Field Simulations: MHF^® 7S harness with cable clamp and clip provides optimal EMC solution. Ideal for 5G mmWave applications.

3) i-Fit^® Technology

3-1) What is i-Fit^® Technology?

 

3-2) i-Fit exceeds precision of solder

I-PEX's i-Fit solderless terminating technology vs. solder termination outperforms in a side-by-side VSWR comparison. Solder processes introduce variability and inconsistency from harness-to-harness. The i-Fit method removes the variability of solder thereby increasing the repeatability and precision of electrical performance.

i-Fit^® offers consistently tight range of performance

 

3-3) Industry adoption

 

3-4) Fully Automated Harness Solutions from I-PEX

I-PEX sells completed MHF^® harnesses in multiple configurations MHF^®-to-MHF^®, blunt cut, strip and tinned. Other value-added options include orientation in 90-degree increments, jacket cut-outs or windows for grounding, adding MP-A clamps or a secondary process at the customer's facility. 
I-PEX specializes and leads in high-speed automated MHF^® harness production. Using custom Fully Automated Machines (FAM), I-PEX FAMs will cut, strip, crimp, check orientation, and perform mechanical and electrical checks. Completing tens of thousands of harnesses per day, I-PEX MHF^® automated equipment have unparalleled Defects Per Million Opportunities (DPMO) of less than 1.
